Patent attributes
An integrated circuit includes first and second memory cells including a first pull-up transistor each having a body tie coupled to respective first and second well bias voltages. Drain electrodes of the first and second pull-up transistors are coupled to a first true bit line and a first complementary bit line, respectively. A second memory cell includes first and second pull-up transistors each having a body tie coupled to the second and first well bias voltages, respectively. Drain electrodes of the first and second pull-up transistors are coupled to a second true bit line and a second complementary bit line, respectively. The first well bias voltage is lower than the second well bias voltage during a Read-Only Memory (ROM) mode, and the first well bias voltage is the same as the second well bias voltage during a Static Random Access Memory (SRAM) mode.
