    摘要: A memory array includes a first column of memory cells, a second column of memory cells, a first pre-charge circuit, a second pre-charge circuit and a set of input output circuits. The first column of memory cells includes a first bit line, a first word line and a first bit line bar. The second column of memory cells includes the first bit line bar, a second word line and a second bit line. The first pre-charge circuit is coupled to the first bit line. The second pre-charge circuit is coupled to the first bit line bar. The first column of memory cells and the second column of memory cells are configured to share the first bit line bar. The first bit line and the first bit line bar are in a first plane. At least a portion of the first word line and at least a portion of the second word line are in a second plane intersecting the first plane.

    摘要: A circuit includes a first data line, a second data line, a first pulling device, a second pulling device, a third pulling device, and a fourth pulling device. The first pulling device is configured to be activated or deactivated responsive to a first control signal; and is configured to pull a first signal at the first data line toward a voltage level of a first voltage based on a second signal at the second data line when the first pulling device is activated. The second pulling device is configured to be activated or deactivated responsive to a second control signal; and is configured to pull the second signal at the second data line toward the voltage level of the first voltage based on the first signal at the first data line when the second pulling device is activated.

    摘要: A power switch control circuit includes a supply rail configured to supply power to a memory array. A first header switch couples the supply rail to a first power supply that corresponds to a first power domain. A second header switch couples the supply rail to a second power supply that corresponds to a second power domain. A control circuit is configured to receive a select signal and a shutdown signal, and to output control signals to the first and second header switches to selectively couple the first and second header switches to the first and second power supplies, respectively, in response to the select signal and the shutdown signal. The control circuit is configured to output the control signals to the first and second header switches to disconnect both the first and second header switches from the first and second power supplies in response to the shutdown signal and irrespective of the select signal.

    摘要: A clock circuit includes a latch circuit, a memory state latch circuit, a memory state trigger circuit and a clock trigger circuit. The latch circuit is configured to latch an enable signal, and to generate a latch output signal based on a first clock signal. The memory state latch circuit is coupled to the latch circuit, and generates an output clock signal responsive to a first control signal. The memory state trigger circuit is coupled to the memory state latch circuit, and adjusts the output clock signal responsive to the latch output signal or a reset signal. The clock trigger circuit is coupled to the latch circuit and the memory state trigger circuit by a first node, configured to generate the first clock signal responsive to a second clock signal, and configured to control the latch circuit and the memory state trigger circuit based on the first clock signal.
