Abstract
A read control circuit for a read only memory implemented with MOSFETs includes a primary address line for selecting a desired memory cell group, and a secondary address line for selecting a desired data read line in the selected memory cell group. The thus selected data read line is charged to a desired level. Then, an address signal is applied to a desired row address line, whereby a discharging current representing the memory state flows through the selected memory cell and the data read line.
