Simultaneous Operation (Dual CE) (128M Page Flash)
The device features functions that enable reading of data from one memory bank while a program or erase
operation is in progress in the other memory bank (simultaneous operation) , in addition to conventional features
(read, program, erase, erase-suspend read, and erase-suspend program) . The bank can be selected by bank
address (A
21
, A
20
) with zero latency. The device consists of the following four banks :
CE0f control: Bank A : 8 x 4 KW and 31 x 32 KW; Bank B : 96 x 32 KW
CE1f control: Bank C : 96 x 32 KW; Bank D : 8 x 4 KW and 31 x 32 KW.
The possible combinations for simultaneous operation is show as following table. ( (Refer to Figure 11 Bank-to-
Bank Read/Write Timing Diagram.)

Bank 1 (CE0f) Status
16 Mbit
* : Multiple Erase Mode requires multiple sector erase sequence which is followed by writes of the Sector Erase
command to addresses in other sectors desired to be concurrently erased. The time between writes must be
less than “t
TOW
”.
