PURPOSE:To change the direction of data and read by supplying an address value consisting of the high order bit (M-L) bit of a first address value and the low order bit of a second address value at the time of reading and designating the data of a second direction orthogonal with a first direction. CONSTITUTION:At the time of reading to a column direction, a write enable signal WE goes to a high level and a data direction designating signal H/V goes to a low level, the externally inputted address values A0-A10 are shifted by three bits, the address values A3-A10 are supplied to respective memory cell arrays 11-18 as the first address values MA0-MA7, chip select signals R/CS1-R/CS8 are completely brought into the low level, the respective memory cell arrays 11-18 are all selected, the one bit of the output data of the respective memory cell arrays 11-18 selected by the selectors 31-38 of a data direction converting part 30 is collected to have 8 bits by a three state gate 39 based on the address values A0-A2 and read. |
