Memory system having flexible addressing and method using tag and data bus communication

摘要

A non-volatile memory system having a memory controller, an array of memory cells and a memory operation manager. The operation manager carries out memory program, read and erase operation upon receipt of program, read and erase instruction from the controller, typically over a system bus. The address block circuitry is provided in the manager which is capable of performing an memory operation on a single address or on multiple addresses depending upon the state of the address block circuitry as determined by the controller. Multiple addresses can be generated based upon a single address provided by the controller so that sectors of the memory can be programmed or read thereby simplifying memory operations and reducing the overhead of the memory controller.
