  • Patent number: 11929114
    Abstract: A system and method for efficiently resetting data stored in a memory array are described. In various implementations, an integrated circuit includes a memory for storing data, and a processing unit that generates access requests for the data stored in the memory. When access circuitry of the memory array begins a reset operation, it reduces a power supply voltage level used by memory bit cells in a column of the array to a value less than a threshold voltage of transistors. Therefore, the p-type transistors of the bit cells do not contend with the write driver during a write operation. The access circuitry provides the reset data on the write bit lines, and asserts each of the write word lines of the memory array. To complete the write operation, the access circuitry returns the power supply voltage level from below the threshold voltage level to an operating voltage level.

  • Patent number: 11710516
    Abstract: A computer-implemented method includes an act of configuring hardware to cause at least a part of the hardware to operate as a double data rate (DDR) memory controller, and to produce a capture clock to time a read data path, where a timing of the capture clock is based on a first clock signal of a first clock, delay the first clock signal to produce a delayed first clock signal, adjust the delay such that at least one clock edge of the delayed first clock signal is placed nearer to at least one clock edge of at least one data strobe (DQS), or at least one signal dependent on a DQS timing, and produce a modified timing of the capture clock based on the delay of the first clock signal.

  • Patent number: 11687283
    Abstract: The present disclosure includes apparatuses and methods related to memory module interfaces. A memory module, which may include volatile memory or nonvolatile memory, or both, may be configured to communicate with a host device via one interface and to communicate with another memory module using a different interface. Memory modules may thus be added or removed from a system without impacting a PCB-based bus to the host, and memory modules may communicate with one another without accessing a bus to the host. The host interface may be configured according to one protocol or standard, and other interfaces between memory modules may be configured according to other protocols or standards.

  • Patent number: 11681352
    Abstract: A method of controlling a memory device can include: determining, by the memory device, a time duration in which the memory device is in a standby mode; automatically switching the memory device from the standby mode to a power down mode in response to the time duration exceeding a predetermined duration; exiting from the power down mode in response to signaling from a host device via an interface; and toggling a data strobe when data is ready to be output from the memory device in response to a read command from the host device.

  • Patent number: 11664065
    Abstract: The invention provides a dynamic random-access memory (DRAM) and an operation method thereof. The DRAM includes a memory cell array, a temperature sensor, and a refresh logic circuit. The temperature sensor senses a temperature of the DRAM. The refresh logic circuit enters a tRFC based on a refresh command issued by a memory controller to perform an automatic refresh operation on at least one memory cell row of the memory cell array. In a temperature-controlled refresh mode, the refresh logic circuit correspondingly adjusts a number of a plurality of tRAS periods in the tRFC according to a temperature sensing result of the temperature sensor. In a fine granularity refresh mode, the refresh logic circuit correspondingly adjusts the number of the tRAS periods in the tRFC according to a granularity specified by the memory controller.

  • Patent number: 11664067
    Abstract: An integrated circuit device outputs a sequence of differently delayed calibration data timing signals to a DRAM component via a data-signal timing line as part of a timing calibration operation and then stores a delay value, based on at least one of the calibration data timing signals, that compensates for a difference in signal propagation times over the data-signal timing line and a command/address-signal timing line. After the timing calibration operation, the integrated circuit device outputs write data to the DRAM component and outputs a write data timing signal, delayed according to the delay value, to via the data-signal timing line to time reception of the first write data within the DRAM.

  • Patent number: 11644985
    Abstract: Methods, systems, and devices for a low-speed memory operation are described. A controller associated with a memory device may, for example, identify a clock mode for a system clock and determine that a speed of the system clock is below a threshold. The controller may generate (or cause to be generated) an internal data clock signal having a shorter period than an external data clock signal (which may have a speed based on the system clock speed). Also, the controller may use, instead of the external data clock signal, the internal data clock signal to generate data from the memory device, which may provide reduced latency. Further, the controller may deactivate (or cause to be deactivated) an external data clock that generates the external data clock signal.

  • Patent number: 11605407
    Abstract: According to one embodiment, a memory system includes a memory interface circuit. The memory interface circuit has delay circuits, a detection circuit, and a control circuit. One of the delay circuits applies a delay to a data signal. Another delay circuit generates, fora strobe signal, a first delay strobe signal, a second delay strobe signal, and a third delay strobe signal, each with different delay amounts. The detection circuit detects a drift in the timing of the first delay strobe signal with respect to the delayed data signal by using the delay data signal, the first delay strobe signal, the second delay strobe signal, and the third delay strobe signal. The control circuit adjusts the first delay amount, the second delay amount, and the third delay amount in a direction to compensate the drift.

    Abstract: A storage device and a manufacturing method thereof are provided. The storage device includes a first chip and a second chip. The second chip is stacked on the first chip in a third direction. The first chip includes a storage array, and the storage array includes at least one storage block. An occupied area after the first chip and the second chip are stacked can be reduced by constructing a first local bit line decoder block, a second local bit line decoder block, a first word line decoder block, and a second local bit line decoder block in a top view projection area, thereby reducing plane occupied space of the storage device. This is beneficial for minimizing the size of the storage device.
