摘要： A memory device includes at least one bitcell coupled to a local bitline. The at least one bitcell includes first, second, and third sets of a plurality of transistor devices. The first set is configured to form at least one write port. The at least one write port receives digital data. The second set of the plurality of transistor devices is configured as an inverter pair that stores the digital data. The third set of the plurality of transistor devices is configured to form at least one read port. The at least one read port is used to access the digital data from the inverter pair and output the digital data on the local bitline. The plurality of transistor devices consists of an equal number of P-channel transistor devices and N-channel transistor devices.

摘要： Various embodiments provide apparatuses, systems, and methods for a register file array with a plurality of sets of memory cells, wherein individual sets of memory cells of the plurality of sets of memory cells are coupled to a respective local bit line (LBL). A merge circuitry may include a multiplexer with inputs coupled to the respective LBLs, wherein the multiplexer is to couple a selected one of the LBLs to a LBL merge node. Read circuitry may be coupled to the LBL merge node to read data from a first memory cell via the selected LBL. In some embodiments, the LBL may be precharged to a supply voltage (e.g., Vcc) minus a threshold voltage, Vt, of the multiplexer transistor, as opposed to being precharged to Vcc as in prior techniques. Other embodiments may be described and claimed.

摘要： A sense amplifier is provided that comprises, responsive to receiving a set signal to turn on a set device and a precharged voltage level read bit line signal, a keeper device that turns on responsive to receiving a LOW signal from an inverting amplifier and pulls up the voltage at a first node so that a HIGH signal is output onto a global bit line. Responsive to receiving the set signal to turn on the set device and a read bit line signal that is discharging through a read stack path to ground and responsive to the read bit line signal discharging below a first predesigned voltage level, a read assist device in the sense amplifier turns on responsive to receiving a HIGH signal from the inverting amplifier and pulls down the voltage at the first node so that a LOW state is output onto a global bit line.
