SRM2264L10/12

CMOS 64K-BIT STATIC RAM

● Low Supply Current

● Access Time 100ns/120ns

● 8,192 Words × 8 Bits, Asynchronous

■ DESCRIPTION

The SRM2264L10/12 is an 8,192-word × 8-bit asynchronous, static, random access memory on a

monolithic CMOS chip. Its very low standby power requirement makes it ideal for applications requir-

ing non-volatile storage with back-up batteries. The asynchronous and static nature of the memory

requires no external clock or refreshing circuit. Both the input and output ports are TTL compatible,

and the three-state output allows easy expansion of memory capacity.
