Sector Erase
The sector erase function erases one or more sectors in the memory array. (See
quire the system to preprogram prior to erase. The Embedded Erase algorithm automatically
programs and verifies the entire memory for an all zero data pattern prior to electrical erase. After
a successful sector erase, all locations within the erased sector contain FFFFh. The system is not
required to provide any controls or timings during these operations.
