Static RAM is a tube composed of MOS flip

静态RAM是由MOS管组成的触发器电路，每个触发器可以存放1位信息。只要不掉电，所储存的信息就不会丢失。因此，静态RAM工作稳定，不要外加刷新新电路，使用方便。但一般SRAM的每一个触发器是由6个晶体管组成，SRAM芯片的集成度不会太高，目前较常用的有6116（2K×8位），6264（8K×8位）和62256（32K×8位）。6264RAM有8192个存储单元，每个单元为8位字长。-Static RAM is a tube composed of MOS flip-flop circuit, each flip-flop can store one message. Long as it does not brown-out, the stored information will not be lost. Therefore, the static stability in the work RAM, do not refresh plus the new circuit and easy to use. But generally each SRAM trigger is composed of six transistors, SRAM chip integration will not be too high, there are currently more commonly used 6116 (2K × 8 bit), 6264 (8K × 8 bit) and 62256 (32K × 8 bits). 6264RAM have 8192 storage units, each for 8-bit word length.
