Abstract
A device including a plurality of static random-access memory (SRAM) bitcells arranged in rows and columns, wherein the SRAM bitcells comprise fully depleted silicon-on-insulator field effect transistors (FDSOI-FETs). The FDSOI-FETs comprise P-channel-pull-up-transistors, wherein each P-channel-pull-up-transistor comprises a back gate. The device further includes a plurality of bitlines, wherein each bitline is electrically connected to the SRAM bitcells of one of the columns and a plurality of wordlines, wherein each wordline is electrically connected to the SRAM bitcells of one of the rows. The device further includes a bitline control circuit configured to select at least one column for writing, wherein during a write operation a first control signal is applied to the back gates of the P-channel-pull-up-transistors of the at least one column selected for writing and a second control signal to the back gates of the P-channel-pull-up-transistors of the columns not selected for writing.
