<p>PURPOSE:To further access the specific number of memory cells in addition to the specific number of the memory cells by providing an address conversion circuit supplying bit line address data corresponding to the content of a mode switching signal to a multiplexer control circuit. CONSTITUTION:If the mode switching signal MS is a first content, the address conversion circuit 6 control in such a way that a bit line address data ADB controls a multiplexer, and the K number of memory cells H(i,1) among the (NXK) number of memory cells H(i,1)-H(i,NK) connected with a word line Wi in a memory cell array 1 are connected with the K number of data input output lines D1-Dk. Furthermore, if the signal MS is a second content, the circuit 6 controls data ADB in such a way that the signal MS controls the multiplexer 4 and a couple of memory cells except for Kpcs. in the (NXK) number of cells H(i,1)-H(1,NK) are connected with the word line Wi in the array 1.</p> |
