A memory device having an array of memory cells connected to a core voltage level, and access circuitry used to perform a write operation in order to write data into a plurality of addressed memory cells. At least one bit line associated with at least each column in the array containing an addressed memory cell is precharged to the peripheral voltage level prior to the write operation being performed. Word line driver circuitry is then configured to assert a word line signal at the core voltage level on the word line associated with the row of the array containing the addressed memory cells. Write multiplexing driver circuitry asserts a mux control signal to write multiplexing circuitry which then couples the bit line of each addressed memory cell to the write driver circuitry in dependence on the mux control signal identifying which column contains the addressed memory cells.

A driver circuit is provided comprising at least two equal main units (MU) each comprising at least two sub units (SU) coupled to a data output (dout). Each sub unit (SU) is adapted to represent a respective predetermined impedance. Each main unit (MU) is adapted to that, when in a data mode, each sub unit (SU) of the respective main unit (MU) is switchable to either a first or second reference potential depending on a data signal to transmit. Each main unit (MU) is further adapted to that, when in a termination mode, the sub units (SU) of the respective main unit (MU) are switched to either the first or second reference potential such that an output of the respective main unit (MU) is neutral with respect to the driving of the data output (dout) to the first or second reference potential.

Circuits for voltage or current biasing static random access memory (SRAM) bitcells during SRAM reset operations are disclosed. Related systems and methods are also disclosed. To reset a plurality of SRAM bitcells in a single reset operation, a biasing circuit is provided and coupled to the plurality of SRAM bitcells. The biasing circuit is configured to apply a voltage or current bias to the SRAM bitcells during a reset operation after power provided to the SRAM bitcells is collapsed to a collapsed power level below an operational power level. The bias is applied as the power to the SRAM bitcells is restored to an operational power level, thus forcing the SRAM bitcells into a desired state. In this manner, the SRAM bitcells can be reset in a single reset operation without need for an increased drive strength from a reset circuit and without need to provide specialized SRAM bitcells.

A method, system, and computer usable program code for increasing drive strength using various steps. First, a data signal is received at a receiving device. The receiving device determines whether the data is successfully received once the data signal is received at the receiving device. If the receiving device determines that the data signal is unsuccessfully received, the receiving device requests an increase in a signal amplitude of the data signal transmitted by a transmitting device that sent the data signal for increasing the drive strength.
