Information
11.8.6 Erase/Program Timing
Notes:
1. Not 100% tested.
2. Asynchronous read mode allows Asynchronous program operation only. Synchronous read mode allows both Asynchronous and
Synchronous program operation.
3. In asynchronous program operation timing, addresses are latched on the falling edge of WE#. In synchronous program operation timing,
addresses are latched on the rising edge of CLK.
4. See the “Erase and Programming Performance” section for more information.
5. Does not include the preprogramming time.
6. The content in this document is Advance information for the S29WS064N and S29WS128N. Content in this document is Preliminary for the
S29W256N.
