Abstract
The present invention relates to a circuit and method for write recovery control for suppressing malfunctions during a write recovery operation. The circuit is for use in a semiconductor memory device including a plurality of memory cells connected in a matrix form to a plurality of word lines and paired bit lines. The circuit comprises a variable load circuit connected to the bit lines, for controlling the voltage level of the bit lines in response to a write enable signal, a word line selector for selecting a predetermined word line in response to an input address, and a delay controller for providing a delay control signal to the word line selector so as to delay activation of the word line selector during the write recovery operation.
