Abstract
An electrically programmable read only memory device is equipped with a plurality of write-in circuits for concurrently writing a plurality of data bits into memory cells, wherein a write-in controlling unit sequentially produces a plurality of write-in controlling signals supplied to a transfer gate groups for sequentially transferring the data bits to column selectors associate with memory cell blocks so that the peak current in the write-in operation is not increased together with the number of the data bits concurrently written into the memory cells.
