What is disclosed is a novel memory array and process for creating a memory array to reduce wireline variability. The method includes accessing a routing design of a memory array with a plurality of memory cells. Each memory cell in the array includes one or more access devices, and a group of wires electrically connected between one or more of the memory cells and peripheral circuitry (PC). The group of the group of wires is divided into at least one subgroup (N). Next, a capacitance (C, C. . . CN) of each wire in the subgroup (N) is calculated. Continuing further, a maximum capacitance (CMAX) of wires in the subgroup (N) is determined. An add-on capacitance to be added to a number (NA) of the wires in the subgroup (N) is calculated.

A method for programming a Phase Change Material-Content Addressable Memory (PCM-CAM). The method includes receiving a word to be written in a PCM-CAM. The word includes low bits represented by a low resistance state in the PCM-CAM and high bits represented by a high resistance state in the PCM-CAM. The method further includes repeatedly writing the low bits in memory cells of the PCM-CAM until the resistance of the memory cells are below a threshold value, and writing the high bits in memory cells of the PCM-CAM only once.

A system, a method for parallel programming multiple bits of a phase change memory array for high bandwidth. The system and method includes parallel programming scheme wherein a common wordline (WL) is driven with a first pulse of one of: gradually increasing (RESET) or decreasing (SET) amplitudes which control current flow through one or more phase change memory cells associated with the WL. Simultaneously therewith, one or more bitlines (BLs) are driven with one or more second pulses, each second pulse more narrow than that of the first pulse applied to the WL. The starting time of the one or more second pulses may vary with each bitline driven at a time later than, but within the window of the wordline pulse to achieve a programming current suitable for achieving the corresponding memory cell state.

A drive circuit and method for parallel programming a plurality of phase change memory (PCM) cells includes a first signal generator device for generating a slow ramping signal; an adiabatic computing element receives the slow ramping signal and responsively generates an output slow ramping signal in adiabatic fashion, the output slow ramping signal applied to the single wordline conductor associated with each PCM cell of the plurality of cells being programmed in a time interval. Each PCM cell of the plurality being programmed is connected to a respective bitline conductor. A second signal generator generates, during the time interval, one or more bitline signals for input to a respective bitline conductor of a respective PCM cell. A state of the applied slow ramping output signal and the one or more bitline signals during the time interval governs a programmed state of the PCM cell.

An example embodiment is a method for determining a binary value of a memory cell represented by an electrical resistance level of the memory cell. The method includes iteratively charging shunt capacitors having different capacitances until a selected shunt capacitor causes the voltage to decay through the memory cell to a reference voltage within a predetermined time range. A binary value of the most significant bits of the memory cell is determined based on the selected shunt capacitor. The selected shunt capacitor is then charged to a second voltage and the binary value of the least significant bits of the memory cell is determined based on a decay of the second voltage at the selected shunt capacitor through the memory cell.
