Abstract
A semiconductor dynamic RAM provided with an I/O load (5) rendered inactive during a writing cycle comprises a monostable multivibrator (16) for receiving a read/write indicating signal W for indicating reading and writing data from and into a memory cell (2) and outputting a signal W having a shorter duration than that of the signal W at a down edge of the signal W as a trigger. The output signal W of the monostable multivibrator (16) is supplied as a control signal for rendering the I/O load (5) inactive.
