WebMay 6, 2024 · In my project I need to use a serial EEPROM. This EEPROM can be either written in byte mode or page mode. If using the byte mode, it's easy to use, but this will minimize the life time, since the whole page is rewritten after writing one byte in a page. That causes in my case 128 write cycles for each cell when writing a whole page. WebFeb 26, 2024 · In practice, the write will be a read-modify-write. The other interesting spinoff of this technique is that in some applications one could dramatically speed up FLASH writing (3ms v. 16ms in this case) by doing a pre-read, and if all 512 bytes are 0xff, do the page program without the pre-erase.

WebSep 7, 2024 · If there would be byte addressing, the head would read/write a single byte, but due to the speed of the rotation, would have to wait a full rotation to execute the next read/write instruction. An alternative could be to cache the access instructions to optimize the access to continuous bytes in order to avoid waiting for unnecessary rotations.

WebApr 10, 2024 · You could do a check to see if using one page write (of 32 bytes) is faster than 6 times a one byte write. However, it depends if you can change your design so it writes 32 bytes at a time. E.g. by writing 60 seconds 4 times 8 bytes (32 bytes) in one page write, instead of every 15 seconds 8 bytes.
