Flash Memory Block Diagram
A simplified diagram of the flash memory block is shown in
The logic consists of the following sub-blocks:
The FB stores error correction information with each block to perform single-bit error correction and
double-bit error detection on all data blocks.

Flash Array
Contains all stored data. The flash array contains 64 sectors, and each sector contains 33 pages
of data.
Page Buffer
A page-wide volatile register. A page contains 8 blocks of data and an AUX block.
Block Buffer
Contains the contents of the last block accessed. A block contains 128 data bits.
