The MA9264 64k Static RAM is configured as 8192x8 bits and

manufactured using CMOS-SOS high performance, radiation hard,

1.5µm technology. The design uses a 6 transistor cell and has full static operation with

no clock or timing strobe required. Address input buffers are deselected when chip select is in the HIGH state.

SIGNAL DEFINITIONS

A0-12

Address input pins which select a particular eight bit word within the memory array.

D0-7

Bidirectional data pins which serve as data outputs during a read operation and as data inputs during a write operation.

Chip Select, which, at low level, activates a read or write operation. When at a high level it defaults the SRAM to a prechargencondition and holds the data output drivers in a high impedance state.

Write Enable which when at a low level enables a write and holds data output drivers in a high impedance state. When at a high level, it enables a read.

Output Enable which when at a high level holds the data output drivers in a high impedance state. When at a low level, data output driver state is defined by CS, WE and CE. If this signal is not used it must be connected to VSS.

Chip Enable which when at a high level allows normal operation. When at a low level it defaults the SRAM to a precharge condition, disables the input circuits on all input pins and holds the data output drivers in a high impedance state. If this signal is not used it must be connected to VDD.
