摘要: A memory cell includes a write port and a read port. The write port includes two cross-coupled inverters that form a storage unit. The cross-coupled inverters are connected between a first power source signal line and a second power source signal line. The write port also includes a first local interconnect line in an interconnect layer that is connected to the second power source signal line. The read port includes a transistor that is connected to the storage unit in the write port and to the second power source signal line, and a second local interconnect line in the interconnect layer that is connected to the second power source signal line. The second local interconnect line in the read port is separate from the first local interconnect line in the write port.

摘要: A method of forming a memory circuit includes generating a layout design of the memory circuit, and manufacturing the memory circuit based on the layout design. The memory circuit is a four transistor memory cell that includes at least the first pass gate transistor and the first pull up transistor. The generating of the layout design includes generating a first active region layout pattern corresponding to fabricating a first active region of a first pull up transistor, generating a second active region layout pattern corresponding to fabricating a second active region of a first pass gate transistor, and generating a first metal contact layout pattern corresponding to fabricating a first metal contact is electrically coupled to a source of the first pull up transistor.

摘要: A physically unclonable function (PUF) generator includes a first sense amplifier that has a first input terminal configured to receive a signal from a first memory cell of a plurality of memory cells, and a second input terminal configured to receive a signal from a second memory cell of the plurality of memory cells. The first sense amplifier is configured to compare accessing speeds of the first and second memory cells of the plurality of memory cells. Based on the comparison of the accessing speeds, the sense amplifier provides a first output signal for generating a PUF signature. A controller is configured to output an enable signal to the first sense amplifier, which has a first input terminal configured to receive a signal from a bit line of the first memory cell and a second input terminal configured to receive a signal from a bit line of the second memory cell.

摘要: A memory device includes a memory cell electrically connected to a power line and a power supply unit configured to control a voltage level on the power line. The power supply unit receives a control signal corresponding to a write cycle of the memory cell and, responsive to a first state of the control signal, outputs a first voltage level on the power line. Responsive to a second state of the control signal, the power supply unit outputs a second voltage level on the power line, the second voltage level having a magnitude less than a magnitude of the first voltage level.
