Two virtual Banks are chosen from the combination of four physical banks (Refer to “FlexBank
Table” and “Example of Virtual Banks Combination Table” in FUNCTIONAL DESCRIPTION)
Host system can program or erase in one bank, and then read immediately and simultaneously from the other
bank with zero latency between read and write operations.

70 ns maximum access time
Eight 4 K word and sixty-three 32 K word sectors in word mode
Eight 8 K byte and sixty-three 64 K byte sectors in byte mode
Any combination of sectors can be concurrently erased. Also supports full chip erase.

Automatically pre-programs and erases the chip or any sector
Automatically writes and verifies data at specified address
Hardware method for detection of program or erase cycle completion
When addresses remain stable, automatically switch themselves to low power mode.
