ABSTRACT:
A non-volatile memory system having an array of memory cells, a memory controller and a memory operations manager, with the array and memory operations manager typically being implemented in a common integrated circuit separate from an integrated circuit containing the memory controller. The memory operation manager carries out memory read, erase, program and program verify operations in response to receipt of memory read, erase, program and program verify commands, respectively, issued by the memory controller. The program verify operation includes reading an address to be verified and programming the address to be verified with data in the event the address had not been properly programmed. The program verify command obviates the necessity of issuing multiple commands in order to carry out the verify function.
