GRNERAL DESCRIPTION

Industry-standard x 4 pinouts and timing

functions

power supply : T2316405A 2.6V(±0.2V)

T2316407A 3.3V(±0.3V)

All device pins are TTL- compatible.

The T2316405A and T2316407A is a randomly

accessed solid state memory containing 16,777,216

bits organized in a x 4 configuration. It offers Fast

Page mode with Extended Data Output (EDO).

· 2048-cycle refresh in 32 ms.

During READ or WRITE cycles, each of the 4

memory bits (1 bit per I/O) is uniquely addressed

through the 22 address bits, which are entered 11
