Notes : 1. A0~A10/A11 are connected to all DRAMs through buffers
(A10 & A11 are NC for 2K refresh module).
2. All signals including PDs (with exception of RAS#, Data and IDs) are buffered.
3. Each 2Mx32 Block comprises of four 2Mx8 DRAMs.
( All specifications of this device are subject to change without notice.)
