Abstract:
A static single-ended read, differential write random access memory cell comprising bit and nbit lines and a word line, the cell being arranged to be read by enabling the bit line while a voltage of predetermined polarity is applied to the word line and to have a bit written in it by applying only complementary voltages to the bit and nbit lines while the voltage of predetermined polarity is applied to the word line, first and second inverters connected to each other to form a regenerative feedback circuit, each of the inverters including first and second field effect transistors of complementary conductivity types, gate electrodes of the field effect transistors of the first inverter being selectively connected to the bit-line in response to the voltage of predetermined polarity being applied to the word line, gate electrodes of the field effect transistors of the second inverter being connected to the nbit line in response to the voltage of predetermined polarity being applied to the word line, each of the gate electrodes being associated with an insulated gate region, the gate region of the first field effect transistor of the first inverter having a width that is substantially larger than the gate region of the first field effect transistor of the second inverter, the first field effect transistors of the first and second inverters being of the same conductivity type.
