    Huabang is committed to the production and design of memory products, including DRAM products group, memory IC manufacturing group and flash memory IC group. The main products of DRAM include Specialty DRAM, Pseudo SRAM and Low Power SDRAM Mobile RAM series products, which can be widely used in consumer, communication, computer periphery and automobile electronics. In addition, high-level DRAM-GDDR products are locked in personal computers, communications and other four areas. Market for games and multimedia applications. Flash memory products, focusing on low and medium density Parallel and Serial NOR Flash, are widely used in personal computers and peripherals, CD-ROMs, wireless networks, DSL data machines, DVD players, on-board boxes and TV sets.
    SDRAM: Synchronous Dynamic Random Access Memory (SDRAM). Synchronization refers to the synchronization clock required for memory operation, which is the basis for the transmission of internal commands and data. Dynamics refers to the need for constant refreshment of storage arrays to ensure that data is not lost. Random refers to the non-linear sequential storage of data. Store, but freely specify the address for data reading and writing.
    SDRAM has become DRAM because it requires constant Refresh to retain data, because Refresh is the most important operation of DRAM. The current accepted standard is that the upper limit of effective storage time of capacitance data in storage is 64ms (milliseconds, 1/1000 seconds), which means that the cycle time of each line refresh is 64ms. The refresh speed is 64 ms per row. When we look at memory specifications, we often see 4096 Refresh Cycles/64ms or 8192 Refresh Cycles/64ms, where 4096 and 8192 represent the number of rows per bank in the chip. The refresh command is valid for one line at a time, and the sending interval varies with the total number of lines. At 4096 lines, it is 15.625 microseconds (microseconds, 1/1000 milliseconds) and at 8192 lines, it is 7.8125 microseconds. HY57V561620 is 8192 refresh cycles/64ms.
    SDRAM is a multi-bank structure. For example, in a SDRAM module with two banks, one bank can be read immediately while the other bank is pre-charged, so that when the data of the pre-charged bank is read immediately after one reading, it can be read directly instead of waiting. This greatly improves the access speed of memory.
    In order to achieve this function, SDRAM needs to increase the management of multiple banks to realize the pre-charging of banks. In SDRAM with more than two banks, there is usually an additional pin called BAn, which is used to implement the selection among multiple banks.
