Abstract
PURPOSE:To increase the readout speed, by discharge of the column line of memory cell from the address data change to the row line designated. CONSTITUTION:A plurality of row lines 191-19n and column lines 201-20m are arranged in matrix, and the memory element is provided at each crossing. The designation of row and column lines is made at row and column recorders 21, 22. While the row line is designated after the address data A0-Am are changed, the pulse generating circuit 27 generating the pulse in which the signal P is at ''1'' level, is provided. This signal turns on the transistors 261-26m, and the row lines 201- 20m are discharged. Thus, since the row line is discharged during a given time, the delay in the readout speed due to discharge time can be avoided and the readout speed can be increased.
