  • Patent number: 12165740
    Abstract: Methods, systems, and devices for memory traffic monitoring are described. The monitoring may include traffic monitoring of access operations performed at various components of the memory device, or may include sensors that may measure parameters of components of the memory device to detect wear. The traffic monitoring or the parameters measured by the sensors may be represented by a characteristic related to an operational bias of circuits of the memory device. The memory device may use the characteristic (e.g., along with a threshold) to determine whether to adjust a parameter associated with performing access operations received by the memory device, in order to implement a corrective action.

  • Patent number: 12093812
    Abstract: An MRAM-based vector multiplication device, such as can be used for inferencing in a neural network, is presented that is ultralow power, low cost, and does not require special on-chip programming. A crosspoint array has an MRAM cell at each crosspoint junction and periphery array circuitry capable of supplying independent input voltages to each word line and reading current on each bit line. Vector multiplication is performed as an in-array multiplication of a vector of input voltages with matrix weight values encoded by the MRAM cell states. The MRAM cells can be individually programmed using a combination of input voltages and an external magnetic field. The external magnetic field is chosen so that a write voltage of one polarity reduces the anisotropy sufficiently to align the cell state with the external field, but is insufficient to align the cell if only half of the write voltage is applied.

The memory system may write first data to the second row of memory cells, and read second data from the second row of memory cells, based on a stored indication associated with the replacement of rows. The memory device may output an error flag with a first value based at least in part on reading the second data, and the first value of the error flag may indicate that the repair operation was successfully performed based at least in part on the second data matching the first data.

  • Patent number: 11747992
    Abstract: Methods, systems, and devices for memory wear management are described. A device may include an interface controller and a non-volatile memory. The interface controller may manage wear-leveling procedures for memory banks in the non-volatile memory. For example, the interface controller may select a row in a memory bank for the wear-leveling procedure. The interface controller may store data from the row in a buffer in the interface controller. The interface controller may then transfer the data to the non-volatile memory so that the non-volatile memory can write the data to a second row of the memory bank.

  • Patent number: 11743449
    Abstract: An imaging device according to the present disclosure has a stacked chip structure in which at least two semiconductor chips, that are a first semiconductor chip provided with a pixel circuit and a second semiconductor chip including an analog-to-digital (AD) conversion circuit which is provided so as to correspond to the pixel circuit, are stacked. The AD conversion circuit includes a latch circuit that retains a digital code after AD conversion and a transfer circuit that transfers the digital code after AD conversion. Further, a failure detection circuit for detecting a failure of the AD conversion circuit is provided. The failure detection circuit performs failure detection by writing a test pattern for failure detection into the latch circuit via the transfer circuit, then reading the test pattern from the latch circuit via the transfer circuit, and comparing the read test pattern with an expected value.
