Common memory naming rules:

Samsung (Samsung) memory specific meaning interpretation: cases: SAMSUNG

K4S283232E-TC60 SDRAM K4H280838B-TCB0 DDR K4T51163QE-HCE6 DDR2 K4B1G164E-HCE7 DDR3 main meaning:

The first bit - the chip function K, represents the memory chip.   

Second bit - chip type 4, representing DRAM. 9 representative NAND FLASH

The third - bit - a further type of description of the chip, S represents SDRAM, H represents DDR, T represents DDR2, B represents DDR3, and G represents SGRAM.   

Fourth, fifth bits - capacity and refresh rate, memory with the same capacity, uses different refresh rates, and also uses different numbers. 64, 62, 63, 65, 66, 67 and 6A represent the capacity of 64Mbit; 28, 27 and 2A represent the capacity of 128Mbit; 56, 55, 57, 5A represent the capacity of 256Mbit; and the capacity of 512Mbit represents 512Mbit.   

Sixth, seventh bits - the number of pins of the data line, 08 for 8 bit data; 16 for 16 bit data; 32 for 32 bit data; 64 for 64 bit data. Eleventh - line - "".   

The fourteenth, fifteenth bit - the rate of the chip, such as 60 for 6ns; 70 for 7ns; 7B for 7.5ns (CL=3); 7C for 7.5ns (CL=2); 80 for 8NS; 10 for 10ns (66MHz). Know the main meaning of digital memory encoding, get a memory after it is very easy to calculate its capacity. For example, a Samsung DDR memory, which is encapsulated with 18 pieces of SAMSUNGK4H280838B-TCB0 particles. The particle number fourth, fifth bits "28" indicates that the particle is 128Mbits, and the sixth, seventh bit "08" indicates that the particle is 8 bit data bandwidth, so we can calculate that the capacity of the memory bar is 128Mbits (megabit) x 16 /8bits=256MB (megabyte).   

Note: "bit" is "digital", "B" is a byte "byte", and one byte is 8 bits divided by 8. As for memory capacity calculation, there are two cases in the paper: one is non ECC memory, every 8 pieces of 8 bit data width particles can form a memory, another ECC memory, after every 64 bits of data, it also adds 8 bit ECC check code. By checking the code, two bit errors in the memory data can be detected and a error can be corrected. So in the process of calculating the actual capacity, no check bits are calculated, and the actual capacity of the 18 pieces of particles with the function of ECC is 16 multiplied by the actual capacity. At the time of purchase, it is also possible to determine 18 or 9 memory strips of memory particles that are ECC memory.    

Hynix (Hyundai) modern modern memory meaning:

HY57V281620FTP-H (H57V2562GTR-75C version) SDRAM HY5DV641622AT-36 H5DU5162ETP-E3C DDR HYXXXXXXXXXXXXXXXX 123456789101112

Micron (Mei Guang)

To MT48LC16M8A2TG-75 this number to illustrate the micron memory encoding rules. Meaning:

MT - the name of the vendor for Micron.   

48 - the type of memory. 48 represents SDRAM; 46 represents DDR. 47=DDR2 LC - supply voltage. LC stands for 3V; C represents 5V; V represents 2.5V. - 16M8 memory capacity of 128Mbits, the calculation method is: 16M (address) * 8 bit data width. A2 - memory kernel version.   

TG - encapsulation, TG, TSOP encapsulation.   

-75 - the rate of memory work, -75 is 133MHz; -65 is 150MHz. Examples: a MicronDDR memory, with 18 pieces of manufacturing MT46V32M4-75 particle number. The memory supports the ECC function. So each Bank is an odd number of memory particles. The capacity: the capacity of 32M * 4bit * 16 /8=256MB (megabytes).

Infineon (Ying Feiling)

Infineon is a subsidiary of SIEMENS, Germany. At present, there are only two capacities in the domestic market that SIEMENS‘s subsidiary Infineon produces: 128Mbits particles and 256Mbits particles. The number in detail lists its memory capacity and data width. Infineon‘s memory queue organization management pattern is that each particle is composed of 4 Bank. So the size of its memory particles is relatively small, and it is also the easiest to distinguish.

HYB39S128400 is 128MB/4bits, and "128" identifies the size of the particle, and the latter three identifies the memory data width. The other is the same, such as: HYB39S128800 is 128MB/8bits; HYB39S128160 is 128MB/16bits; HYB39S256800 is 256MB/8bits.   

The representation of the working rate of Infineon memory particles is to add a short line at the end of its model and then to mark the working rate.   

-7.5 said the work frequency of the memory is 133MHz; -8 - said the operating frequency of the memory is 100MHz. For example:

1 Kingston memory strips are produced with 16 pieces of Infineon HYB39S128400-7.5 memory particles. Its capacity is calculated as: 128Mbits (megabyte) x 16 pieces of /8=256MB (megabyte).   

1 Ramaxel memory strips are produced with 8 pieces of Infineon HYB39S128800-7.5 memory particles. Its capacity is calculated as: 128Mbits (megabyte) x 8 pieces of /8=128MB (megabyte).    


KINGMAX memory instructions

Kingmax memory is used in TinyBGA encapsulation (Tinyballgridarray). And the encapsulation mode is a patented product, so we see that the memory strips made with Kingmax particles are all produced by the factory itself. Kingmax memory particles have two kinds of capacity: 64Mbits and 128Mbits. Here you can list the memory particle sizes of each capacity series. Note: capacity

KSVA44T4A0A, 64Mbits, 16M address space X 4 bit data width; KSV884T4A0A - 64Mbits, 8M address space X 8 bit data width; KSV244T4XXX - 128Mbits, 32M address space X 4 bit data width; KSV684T4XXX - 128Mbits, 16M address space X 8 digits according to width; KSV864T4XXX - 128Mbits. The address space of 8M x 16 bit data width. There are four types of Kingmax memory work rate, is used in the models of short-term memory work rate identification symbols separated by:

-7A - PC133/CL=2 -7 - PC133/CL=3;; -8A - PC100/CL=2 -8 - PC100/CL=3.   

For example, a Kingmax memory bar is made of 16 KSV884T4A0A-7A memory particles, and its capacity is calculated as 64Mbits (megabit) x 16 /8=128MB (megabyte).     

Winbond (Hua Bang) meaning: WXXXXXXXX 12345

TI product classification and Description:

The company has a large number of semiconductor products, including memory product group, digital signal processor (DSP), power management IC, amplifier and linear device, microcontroller, data converter, temperature sensor and control IC, standard linear device and so on. In terms of our daily enquiries, I will first introduce the three types of digital signal processor (DSP), micro controller and power management IC.

Digital signal processor (DSP):

The DSP (digital singnal processor) chip, also known as the digital signal processor, is a microprocessor with a special structure. The DSP chip adopts the Harvard structure separated from program and data. It has special hardware multiplier, widely used pipeline operation, providing special DSP instructions, which can be used to realize all kinds of digital signal processing algorithms quickly. According to the requirements of digital signal processing, DSP chips generally have the following main features:

(1) a multiplication and one addition can be completed within an instruction cycle.

(2) the program is separated from the data space, and the instructions and data can be accessed at the same time.

(3) there is a fast RAM in the chip, which can usually be accessed at the same time through an independent data bus in two blocks.

(4) hardware support with low overhead or no overhead cycle and jump.

(5) fast interrupt handling and hardware I/O support.

(6) multiple hardware address generators operating in a single cycle.

(7) multiple operations can be executed in parallel.

(8) support pipelining so that operations such as reference, decoding, and execution can be overlapped.

Compared with common microprocessors, the other general functions of DSP chips are relatively weak.
