摘要: A circuit includes a bitcell array having a plurality of bitlines, and an I/O functional unit to read data stored in the bitcell array. The I/O functional unit includes a first multiplexer to select a first input port or a first bitline among a first group of bitlines, a first latch to latch the output of the first multiplexer, a second multiplexer to select a second input port or a second bitline among a second group of bitlines. The second input port is coupled to an output port of the first latch. The I/O functional unit further includes a second latch to latch the output of the second multiplexer.

摘要: Various implementations described herein may refer to and may be directed to non-discharging read-only memory cells. For instance, in one implementation, an integrated circuit may include a read-only memory (ROM) array including a plurality of ROM cells arranged into a column, where the column is disposed proximate to a bit line and to a reference voltage line. The plurality of ROM cells arranged into the column may include a plurality of non-discharging ROM cells positioned adjacently to one another, where each non-discharging ROM cell has a source terminal, a drain terminal, or both coupled to at least one adjacent non-discharging ROM cell. In addition, the plurality of non-discharging ROM cells may be coupled to the bit line using two or fewer connections.

摘要: A memory device and method of operating a memory device are provided. The memory device comprises global control circuitry configured to receive a clock signal for the memory device and the memory device is configured to perform a double memory access in response to a single edge of the clock signal. A first internal clock pulse for a first access of the double memory access and a second internal clock pulse for a second access of the double memory access are generated in response to the single edge of the clock signal. The global control circuitry generates a comparison signal in dependence on a comparison between a first bank indicated by the first access and a second bank indicated by the second access, and local bank control circuitry of the second bank is configured to generate the second internal clock pulse in dependence on the comparison signal.

摘要: Various implementations described herein are directed to an integrated circuit. The integrated circuit may include core circuitry having an array of memory cells and a row decoder that accesses each of the memory cells via a selected wordline and a wordline signal. The core circuitry may operate at a first supply voltage. The integrated circuit may include periphery circuitry having a column decoder that accesses each of the memory cells via a selected bitline. The periphery circuitry may operate at a second supply voltage that is different than the first supply voltage. The periphery circuitry may include voltage differential sensing circuitry that may compare the first supply voltage to the second supply voltage, sense a voltage differential between the first and second supply voltages, and delay the wordline signal when the voltage differential is greater than a threshold voltage.
