Commands are written using standard micro-
processor write timings. The CUI contents serve
as input to the WSM that controls the block
erase, programming, and lock-bit configuration.
The internal algorithms are regulated by the
WSM,
including
pulse
verification, and margining of data. Addresses
and data are internally latched during write
cycles. Writing the appropriate command outputs
array data, identifier codes, or Status Register
data.

Interface software that initiates and polls
progress of block erase, programming, and lock-
bit configuration can be stored in any block. This
code is copied to and executed from system
RAM during flash memory updates. After
successful completion, reads are again possible
via the Read Array command. Block erase
suspend allows system software to suspend a
block erase to read or write data from any other
block. Program suspend allows system software
to suspend a program to read data from any
other flash memory array location.

Data Protection
Depending on the application, the system
designer may choose to make the V

device supports either design practice, and
encourages optimization of the processor-
memory interface.

provides additional protection from inadvertent
