Appl. No.:

12/578917

Inventors:

Phat Truong - Houston TX, US
Tien Dinh Le - Sugar Land TX, US

Assignee:

Nanya Technology Corp. - Tao-Yuan Hsien

International Classification:

G11C 8/18

US Classification:

36523313, 36523312, 36523316, 3652331, 365193, 365194

Abstract:

A method is provided for writing data to a memory array operating in synchronization with a clock signal having a transition edge. A data strobe signal having a transition edge corresponding to the transition edge of the clock signal is provided. The transition edge of the clock signal is used to relay the data corresponding to the transition edge of the data strobe signal if the transition edge of the data strobe signal is coming in earlier than the transition edge of the clock signal, wherein the clock signal has a rising edge and a falling edge, the data strobe signal has a rising edge and a falling edge respectively corresponding to the rising and the falling edges of the clock signal, and the transition edge of the clock signal is one of the rising and the falling edges of the clock signal.

Abstract:

A method is provided for relaying data to a memory array operating in synchronization with a clock signal having a first transition edge. A data strobe signal having a second transition edge corresponding to the first transition edge is provided. A first signal is provided. The data is latched into the first signal at a first time point lagged behind the first transition edge by a first time interval until a second time point in response to the first transition edge for relaying the data of the first signal to the memory array when the second transition edge appears earlier than the first transition edge.
