RADIATION HARD 4096 x 1 BIT STATIC RAM

DS3580-3.2

The MA5104 4k Static RAM is configured as 4096 x 1 bits and

manufactured using CMOS-SOS high performance, radiation hard,

3µm technology.

The device has separate input and output terminals controlled by

Chip Select and Write Enable. 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.
