1. A non-volatile memory device comprising:
- a memory cell array including memory cells distributed among a plurality of sectors;
a controller operable to program, read, and erase memory cells in said memory array, said controller further operable to generate and store EPLI values, and to program a number of EPLI bits in one of said plurality of sectors with said stored EPLI values; and
a comparator to compare said stored EPLI values with said EPLI values programmed in said EPLI bits.

Abstract
A non-volatile memory device comprising a memory cell array including memory cells distributed among a plurality of sectors; a controller operable to program, read, and erase memory cells in said memory array, said controller further operable to generate and store EPLI values for programming a number of EPLI bits in one of said plurality of sectors with said stored EPLI values; and a comparator to compare said stored EPLI values with EPLI values programmed in said EPLI bits.

17. A method of erasing a sector of non-volatile memory cells in a non-volatile memory device comprising:
-
generating and storing initial EPLI values and final EPLI values; programming EPLI bits inside the sector with said initial EPLI values; and executing a memory sector erase flow; wherein said memory sector erase flow includes at least the steps of memory cell pre-programming, erasing, and soft-programming. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
