    摘要: A memory device is provided, including a memory array, a driver circuit, and recover circuit. The memory array includes multiple memory cells. Each memory cell is coupled to a control line, a data line, and a source line and, during a normal operation, is configured to receive first and second voltage signals. The driver circuit is configured to output at least one of the first voltage signal or the second voltage signal to the memory cells. The recover circuit is configured to output, during a recover operation, a third voltage signal, through the driver circuit to at least one of the memory cells. The third voltage signal is configured to have a first voltage level that is higher than a highest level of the first voltage signal or the second voltage signal, or lower than a lowest level of the first voltage signal or the second voltage signal.

    摘要: A memory device is provided, including a first bit cell including a first memory cell coupled to a first word line and a second bit cell including a second memory cell coupled to a second word line. The first and second memory cells are coupled to a first control line and further coupled to a first bit line through first and second nodes. The second bit cell further includes a first protection array coupled to the second memory cell at the second node coupled to the first bit line and further coupled to a third word line. When the first and second bit cells operate in different operational types, the first protection array is configured to generate an adjust voltage to the second node according to a voltage level of the third word line while the first bit cell is programmed.

    摘要: A memory device is disclosed, including a bit cell storing a bit data. The bit cell includes multiple first transistors coupled to a node, multiple second transistors each coupled in series to a corresponding one of the first transistors, and at least one third transistor. The first transistors are turned on in response to a control signal. The second transistors are turned on in response to a first word line signal. The at least one third transistor has a control terminal to receive a second word line signal. In a programming mode of the memory device, the at least one third transistor provides, in response to the second word line signal, an adjust voltage to the node. The adjust voltage is associated with a voltage level of a first terminal of the at least one third transistor.

    摘要: A ferroelectric field-effect transistor (FeFET) configured as a multi-bit storage device, the FeFET including: a semiconductor substrate that has a source region in the semiconductor substrate, and a drain region in the semiconductor substrate; a gate stack over the semiconductor substrate, with the source region and the drain region extending to opposite sides of the gate stack, the gate stack including a ferroelectric layer over the semiconductor substrate, and a gate region over the ferroelectric layer. The transistor also includes first and second ends of the ferroelectric layer which are proximal correspondingly to the source and drain regions. The ferroelectric layer includes dipoles. A first set of dipoles at the first end of the ferroelectric layer has a first polarization. A second set of dipoles at the second end of the ferroelectric layer has a second polarization, the second polarization being substantially opposite of the first polarization.

    摘要: Disclosed herein are systems, methods and apparatuses related to a memory array. In one aspect, the memory array includes a set of resistive storage circuits including a first subset of resistive storage circuits connected between a first local line and a second local line in parallel. The first local line and the second local line may extend along a first direction. In one aspect, for each resistive storage circuit of the first subset of resistive storage circuits, current injected at a first common entry point of the first local line exits through a first common exit point of the second local line, such that each resistive storage circuit of the first subset of resistive storage circuits may have same or substantial equal resistive loading.
