Program and erase times and endurance cycles
The program and erase times and the number of program/erase cycles per block are shown
in Table 16. Exact erase times may change depending on the memory array condition. The
best case is when all the bits in the block are at ‘0’ (preprogrammed). The worst case is
when all the bits in the block are at ‘1’ (not preprogrammed). Usually, the system overhead is
negligible with respect to the erase time. In the M58LT128HST/B the maximum number of
program/erase cycles depends on the V voltage supply used.
