Intel StrataFlash Wireless Memory (L18)
Order Number: 251902, Revision: 009
Datasheet
14.2.1
Simultaneous Operation Details
The Intel StrataFlash Wireless Memory (L18) supports simultaneous read from one partition
while programming or erasing in any other partition. Certain features like the Protection Registers
and Query data have special requirements with respect to simultaneous operation capability. These
will be detailed in the following sections.
14.2.2
Synchronous and Asynchronous RWW Characteristics and
Waveforms
This section describes the transition of write operation to asynchronous read, write to synchronous
read, and write operation with clock active.
14.2.2.1
Write operation to asynchronous read transition
W18 - t
WHAV
The AC parameter W18 (t
WHAV
-WE# High to Address Valid) is required when transitioning from a
write cycle (WE# going high) to perform an asynchronous read (only address valid is required).
