Preliminary

Description

The AT45DB321 is a 2.7-volt only, serial interface Flash memory suitable for in-sys-

tem reprogramming. Its 34,603,008 bits of memory are organized as 8192 pages of

528 bytes each. In addition to the main memory, the AT45DB321 also contains two

SRAM data buffers of 528 bytes each. The buffers allow receiving of data while a

page in the main memory is being reprogrammed. Unlike conventional Flash memo-
