Method and system for accessing a flash memory device

摘要

An apparatus, system, and computer-implemented method for controlling data transfer between a plurality of serial data link interfaces and a plurality of memory banks in a semiconductor memory is disclosed. In one example, a flash memory device with multiple links and memory banks, where the links are independent of the banks, is disclosed. The flash memory devices may be cascaded in a daisy-chain configuration using echo signal lines to serially communicate between memory devices. In addition, a virtual multiple link configuration is described wherein a single link is used to emulate multiple links.

1. A semiconductor memory device comprising:
a plurality of flash memory blocks, each of the flash memory blocks having respective row decoding circuitry and respective sense amplifier circuitry; and an at least one interface, operable to: i) commonly receive both address and command data at an input port of the at least one interface; ii) address the flash memory blocks; and iii) initiate operations performed in at least two of the flash memory blocks in overlapping time periods, and the at least one interface and the flash memory blocks being provided in a single chip of the semiconductor memory device.
