8 PCS. LH21256-12 Dynamic Ram 256K x 1 Sharp

The LH21256 is a 262,144 word × 1 bit dynamic RAM fabricated using N-channel 2-layer polysilicon 
gateprocess technology. With mulitiplexed address inputs, it is easy to comprise memory systems with high speed, low power consumption and large memory capacity. 
The LH21256 operates on a single +5 V power supply. The built-in high output substrate bias generator circuit eliminates sensitivity to undershoot on the input signals.
