    ISSI is Integrated Silicon Solution, Inc. Established in 1988, it specializes in the design, development and sale of high-performance storage semiconductor products for Internet memory devices, network devices, remote communications and mobile communications equipment, computer peripherals, etc.

    SDRAM: synchronous dynamic random access memory (SRAM), synchronization means that the memory work needs a synchronous clock, the transmission of the internal command and the transmission of the data are based on it; the dynamic is that the storage array needs to be refreshed continuously to ensure that the data is not lost; random is that the data is not stored in linear order, but the data is freely assigned to the address for data. Read and write.
    SDRAM becomes DRAM because it needs to constantly refresh (Refresh) to retain data, because refresh (Refresh) is the most important operation of DRAM. So how long does it take to repeat the refresh time? The current standard is that the upper limit of the effective storage time for the data is 64ms (milliseconds, 1/1000 seconds), that is to say, the cycle of each row is 64ms. This refresh speed is: the number of 64ms/ lines. When we look at the memory specifications, we often see the identifier of 4096 Refresh Cycles/64ms or 8192 Refresh Cycles/64ms, and 4096 and 8192 here represent the number of rows per Bank in this chip. The refresh command is valid for one line at a time, and the transmission interval varies with the number of lines. The 4096 line is 15.625 s (microseconds, 1/1000 milliseconds), and the 8192 line is 7.8125 s. HY57V561620 is 8192 refresh cycles / 64ms.
    SDRAM is a multi Bank structure, such as in a module with two Bank SDRAM, of which one of the Bank is precharged and another Bank can be read immediately, so that when a read is carried out, and immediately read the data that has been precharged Bank, it does not need to wait but read directly. The access speed of the memory is greatly improved.
    In order to achieve this function, SDRAM needs to increase the management of multiple Bank and realize the precharge of Bank in control. In a SDRAM with more than 2 Bank, a pin called BAn is usually used to achieve the choice between multiple Bank.
