S29GL064N Erase Times

Page 70 of the data sheet....

Does the chip erase all sectors simultaneously when doing a sector erase? Sector erase typ = .5 sec... x 128 for all sectors = 64 sec for a chip erase. This makes sense but why isn't the max chip erase time 3.5 seconds x 128 sectors? Is it correct to say that if I erase 10 sectors it would typically take 10 x .5 sec = 5 seconds?

Thanks!

Hello,

The typical is representing an early life Prog/Erase life cycle performance. The Max is for a sector has been excessive gone thru Prog/Erase cycles, the Erase time is generally getting longer over program/erase cycles.

Regarding to 2^nd question: Yes, the typical erase time of the 10 sectors are about 5 seconds (10 x 0.5 sec).

I would also encourage you to leverage the data polling to determine the status of the erase operation rather depending on the stopwatch timeout.

Thank you

Regards,

Bushra
