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 17. 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’ (pre-programmed). 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 M58LR128HT/B the
maximum number of Program/Erase cycles depends on the VPP voltage supply used.
