5. MEMORY ORGANIZATION
5.1. Flash Memory Array
The
HM25Q40A memory is organized as:
- 524,288bytes
- Uniform Sector Architecture 8 blocks of 64-Kbyte
- 128 sectors of 4-Kbyte
- 2, 048 pages (256 bytes each)
Each page can be individually programmed (bits are programmed from 1 to 0). The device is Sector,
Block or Chip Erasable but not Page Erasable.
