Abstract
A buffer is provided that has a high access time and operates with reduced power consumption. The buffer includes n write word line registers ( ), each of which an output is directly connected to a word line driver. Thus, a word line is driven to access a memory cell array. All the word line registers are cascaded in a ring form. The write START signal acting as a synchronous set input is input to the write word line register ( ) corresponding to the least significant address. The write strobe (STB) signal is input to the write word line registers connected in a ring form. When the write strobe signal is active, the write word line registers operate like a shift register. When the write strobe signal is not active, all the write word line registers hold a current value.
