    摘要: The present invention relates to a row address strobe signal generating device for a semiconductor memory device, and in particular a row address strobe signal generating device which can prevent a cell data from being destroyed during a data maintenance time, by sufficiently obtaining a writing time of the cell data. The row address strobe signal generating device includes a write recover signal generating device, and thus controls a disable state of a row address strobe signal during a write operation. Accordingly, the row address strobe signal is disabled only after a write recover signal is disabled. As a result, a cell data writing time is sufficiently obtained in a high speed memory, and thus the stored cell data is not destroyed during the data maintenance time.
