Notes :
1. Each 256Kx36 block comprises of two 256Kx18 SRAM devices.
2. A0~A17 to all SRAM devices.
3. CE2 & CE2# of all devices are tied active.
4. All other unused control signals are tied inactive except for BWE
signal on parity devices, which is tied active.
( All specifications of this device are subject to change without notice.)
