A memory matrix is divided into a plurality of zones, one of which has a predetermined address and is set aside for a control character having multiple bits, stored in plural cells of the one zone. Each cell stores electric charge, with the cells in the control zone storing a charge no greater than that in the remaining zones. After the cells of the control zone have been initially supplied with the predetermined control character, the cells of the control zone are isolated from write command signals during normal operation. The cells of the control zone can be read out during normal operation.
