Simultaneous Read/Write

The simultaneous read/write feature allows the host system to read data from one bank of mem-

ory while programming or erasing another bank of memory. An erase operation may also be

suspended to read from or program another location within the same bank (except the sector

being erased). Figure 11.12, Back-to-back Read/Write Cycle Timings shows how read and write

cycles may be initiated for simultaneous operation with zero latency. See the table, DC Charac-

teristics for read-while-program and read-while-erase current specifications.

Note: Amax = A23 (PL256N), A22 (PL127N)
