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 flash memory device comprising:
a flash memory array; a page buffer to receive read data from the flash memory array; a clock input pin to receive a clock signal; and a data interface to provide the read data in the page buffer on a first number of first edges of the clock signal, and to receive command data at the data interface, the data interface including: a common command and data input to receive input data and the command data at different times; and a control input pin to receive a control signal set to a logic level for a same number of second edges of the clock signal as the first number of the first edges, and the control signal to enable the data interface to provide the read data.
