Abstract
PURPOSE:To extend an access time and to reduce a program load for address specification, by providing a read-only memory element with a memory address register which increases automatically. CONSTITUTION:According to addresses stored in an address register 6, data are read out of a memory cell matrix 2 by an address decoder 1, and then outputted to data terminals D0-D7 through a data output buffer 3 by a data output control signal 11 generated by a writing-reading control circuit 7. As a readout indication signal is ceased, an address count signal 10 is generated and applied to the address register 6, whose contents, i.e., address increases by one. Consequently, data in successive addresses are read without external operation.
