Abstract
A virtual ground memory which has four state cells coupled to bit lines has a load directly connected to each bit line to reduce the degradation of the output of a selected memory cell due to voltage drop caused by current flow between load and selected memory cell. Additionally, loads which are coupled to the bit lines are also coupled to an adjacent virtual ground line to avoid providing a separate power supply line for the loads.
