Title:
信号デコーディング装置及びその方法
Document Type and Number:
Japanese Patent JP4446295
Kind Code:
B2
Abstract:
An apparatus and method for decoding address signals. The apparatus generally comprises an address buffer array, a buffer controller coupled to the address buffer array, an address decoder coupled to the address buffer array and a strobe generator coupled to the address decoder and the buffer controller. The address buffer array buffers address signals in response to an address strobe from the buffer controller. The strobe generator generates a decoding strobe in response to the address strobe. The decoding strobe signals the address decoder to decode the address signals received from the address buffer array. To synchronize the arrival of the decoding strobe and the buffered address signals at the decoder, the strobe generator has one or more signal transfer characteristics in common with one or more of the address buffers. In a specific embodiment, the strobe generator has a longer signal transfer delay than any address buffer in the address buffer array. Thus, the decoding strobe determines an input timing margin of the address decoder.
