  • Publication number: 20230420017
    Abstract: Computer memory arrays employing memory banks and integrated serializer/de-serializer circuits for supporting serialization/de-serialization of read/write data in burst read/write modes, and related methods are disclosed. The memory array can include a serialization circuit configured to convert parallel data streams of read data received from separately switched memory banks into a single, serialized, read data stream in a burst read mode. The memory array can also include a de-serialization circuit configured to convert a received, serialized write data stream on an input bus for a write operation into separate, parallel write data streams to be written simultaneously to the memory banks in a burst write mode.

  • Patent number: 11418175
    Abstract: The present disclosure relates to a reciprocal quantum logic (RQL) inverter including an inverter bias tap, a pulse generating Josephson junction (JJ), and a superconducting quantum interference device (SQUID) based structure, which includes a SQUID JJ and is connected between the inverter bias tap and the pulse generating JJ. The SQUID based structure is configured to receive an inverter bias signal from the inverter bias tap and receive a data input from a previous circuit stage. When the data input is at logic state “0,” the pulse generating JJ can be triggered so as to provide an output signal with logic state “1.” When the data input is at logic state “1,” the first SQUID JJ can be triggered thereby preventing the pulse generating JJ from be triggered, such that the output signal is provided at logic state “0.

  • Patent number: 9196330
    Abstract: Systems and methods for adaptively mimicking wordline decoding logic for multi-voltage domain memory are disclosed. In one embodiment, the multi-voltage domain memory includes a memory array implemented in a high voltage domain and a multi-voltage domain control circuit. The multi-voltage domain control circuit includes multi-voltage domain decoding logic that generates a wordline for the memory array and a multi-voltage domain mimic logic that mimics the multi-voltage domain decoding logic to generate a dummy wordline. In one embodiment, the dummy wordline is utilized to trigger an ending edge (e.g., a falling edge) of the wordline once the wordline is asserted. In addition or alternatively, the dummy wordline is utilized to generate one or more control signals for the memory array such as, for example, a pre-charge control signal and/or a sense amplifier enable signal.

  • Publication number: 20140337573
    Abstract: Embodiments disclosed include redirecting data from a defective data entry in memory to a redundant data entry prior to data access. Related systems and methods are also disclosed. The memory is configured to receive a memory access request. The received memory access request comprises a data entry address. The memory uses the data entry address to access data stored in a data array in the memory in a first data access path. It is possible that the rows or columns in the memory may be defective as a result of a manufacturing process. In the event that a row or column at the data entry address in the data array is defective, a data entry redirection circuit redirects the memory access request to a redundant row or column in the data array prior to data access.

  • Patent number: 6473334
    Abstract: A multi-ported SRAM memory cell includes a pair of inverters that holds the data bit. The state terminals of the memory cell connect via a separate read and write data path to the bit lines. The read bit lines connect to a pull-down transistor stack. The first transistor in the stack is gated by the word line, and the second transistor is gated by the state terminal of the memory cell. If the word line is asserted and the second transistor is turned on by the state of the memory cell, the bit line is connected to ground, thus pulling the bit line low. Conversely, if the second transmitter is not turned on, the bit line stays at a high voltage level. In a preferred embodiment, the memory cell is isolated from the pull-down transistor stack by an isolation buffer, such as an inverter, which inverts the voltage on the state terminal of the memory cell.
