<p>PURPOSE:To eliminate the need of an externally fitted circuit and to decrease the installing space of components, the cost and the trouble of an assembling work by building in the time width shortening means of a chip selecting signal. CONSTITUTION:An address signal to select one of memory cells in a memory cell array 11 is supplied to an input terminal (a), a chip selecting signal CS to operate selectively the memory element is supplied to an input terminal (d) and supplied to a latch circuit 15 and a resetting control circuit 16 arranged in a memory element 10. The latch circuit 15 latches the chip selecting signal CS, and supplies a chip selecting signal cs with the time width shorter than this to a low address decoder 12 and a column address decoder 13. Thus, the time width shortening means of the chip selecting signal is built in, the externally fitted circuit therefor is eliminated, and the installing space of the components, the cost and the trouble of assembling work are effectively decreased.</p> |
