Apparatus comparing verified data to original data in the programming of memory cells

摘要

Apparatus configured to perform a programming operation on a row of memory cells in response to original data, configured to perform a comparison of verified data of the row of memory cells to the original data following success of the programming of the row of memory cells, and further configured to perform a post-programming program operation on the row of memory cells if the verified data is different from the original data.

主权项

1. A memory module comprising:
at least two non-volatile memory devices, each device comprising:
a memory array having a plurality of non-volatile memory cells coupled to word lines and bit lines;a plurality of cache registers for inhibiting programming of a column of memory cells, each cache register coupled to a pair of bit lines;a plurality of data caches for storing data to be programmed, each data cache coupled to the pair of bit lines; anda memory controller circuit coupled to the memory array, the controller circuit configured to execute a method for programming the plurality of memory cells such that the controller circuit generates a series of program and verify pulses to program original data into a row of memory cells, sets each respective cache register in response to a successful verification, performs a subsequent verification operation to determine verified data, and performs a post-programming program operation on the row of memory cells if the verified data is different from the original data; and a plurality of contacts configured to provide selective contact between the memory devices and a host system.
