Description
A64S16161 is a virtually static RAM, which uses DRAM type memory cells, but it has refresh transparency, so that you need
not to imply refresh operation. Furthermore the interface is completely compatible to a low power Asynchronous type SRAM, you
can operate as same as the Asynchronous SRAM.
A64S16161 is a 2,097,152 Words X 16 bit asynchronous random access memory on a monolithic CMOS chip with
marvelous low power consumption technology. Its low power and also low noise makes it ideal for mobile applications.
