Multi-Bit Flash Memory Devices and Methods of Programming and Erasing the Same |
摘要 |
A non-volatile memory device includes an array of non-volatile memory cells configured to support single bit and multi-bit programming states. A control circuit is provided, which is configured to program a first page of non-volatile memory cells in the array as M-bit cells during a first programming operation and further configured to program the first page of non-volatile memory cells as N-bit cells during a second programming operation. The first and second programming operations are separated in time by at least one operation to erase the first page of non-volatile memory cells. M and N are unequal integers greater than zero.
