Utilizing an array of six transistors (6T) memory cells, the M65608E combines an extremely low standby supply current (Typical value = 0.2 µA) with a fast access time at 30 ns over the full military temperature range. The high stability of the 6T cell provides excellent protection against soft errors due to noise. The M65608E is processed according to the methods of the latest revision of the MIL PRF 38535 or ESCC 9000. Rad.

Data retention voltage and supply current are guaranteed over temperature. The following rules ensure data retention: 1. During data retention chip select CS1 must be held high within VCC to VCC 0.2V or, chip select CS2 must be held down within GND to GND +0.2V. 2. Output Enable (OE) should be held high to keep the RAM outputs high impedance, minimizing power dissipation. 3. During power up and power-down transitions CS1 and OE must be kept between VCC + 0.3V and 70% of VCC, or with CS2 between GND and GND -0.3V. 4. The RAM can begin operation > TR ns after VCC reaches the minimum operation voltages (4.5V).

Both signals must be actived to initiate a write and either signal can terminate a write by going in actived. The data input setup and hold timing should be referenced to the actived edge of the signal that terminates the write.
