PURPOSE:To obtain a control system so as to reduce a write time, by performing the initial set at a bundle. CONSTITUTION:At RAS (Row Address Strobe) only, a word line of an address multiplex memory kept opened is used to set logical RAS having an external data to a common I/O, Column Address Strobe and Write Enable signals. Then, the initial set is performed at every word line, not at every bit, and even if the memory capacity is large, the write time is decreased with the semiconductor memory write control system. |
