  • Publication number: 20210335437
    Abstract: A method of operation in an integrated circuit (IC) memory device is disclosed. The method includes refreshing a first group of storage rows in the IC memory device at a first refresh rate. A retention time for each of the rows is tested. The testing for a given row under test includes refreshing at a second refresh rate that is slower than the first refresh rate. The testing is interruptible based on an access request for data stored in the given row under test.

  • Patent number: 11114150
    Abstract: A dynamic random access memory (DRAM) component (e.g., module or integrated circuit) can be configured to have multiple rows in the same bank open concurrently. The controller of the component divides the address space of the banks into segments based on row address ranges. These row address ranges do not necessarily correspond to row address ranges of the bank's subarrays (a.k.a. memory array tiles—MATs). When a command is sent to open a row, the controller marks a plurality of the segments as blocked. The controller thereby tracks address ranges in a bank where it will not open a second row unless and until the first row is closed. The memory component may store information about which, and how many, segments should be blocked in response to opening a row. This information may be read by the controller during initialization.

  • Publication number: 20210157582
    Abstract: An array of processing elements are arranged in a three-dimensional array. Each of the processing elements includes or is coupled to a dedicated memory. The processing elements of the array are intercoupled to their nearest neighbor processing elements. A processing element on a first die may be intercoupled to a first processing element on a second die that is located directly above the processing element, a second processing element on a third die that is located directly below the processing element, and the four adjacent processing elements on the first die. This intercoupling allows data to flow from processing element to processing element in the three directions. These dataflows are reconfigurable so that they may be optimized for the task. The data flows of the array may be configured into one or more loops that periodically recycle data in order to accomplish different parts of a calculation.

  • Patent number: 11012649
    Abstract: A control pulse is generated a first control signal line coupled to a transfer gate of a pixel to enable photocharge accumulated within a photosensitive element of the pixel to be transferred to a floating diffusion node, the first control signal line having a capacitive coupling to the floating diffusion node. A feedthrough compensation pulse is generated on a second signal line of the pixel array that also has a capacitive coupling to the floating diffusion node. The feedthrough compensation pulse is generated with a pulse polarity opposite the pulse polarity of the control pulse and is timed to coincide with the control pulse such that capacitive feedthrough of the control pulse to the floating diffusion node is reduced.

  • Publication number: 20210098033
    Abstract: Row activation operations within a memory component are carried out with respect to subrows instead of complete storage rows to reduce power consumption. Further, instead of activating subrows in response to row commands, subrow activation operations are deferred until receipt of column commands that specify the column operation to be performed and the subrow to be activated.

  • Publication number: 20210089237
    Abstract: An memory component includes a memory bank and a command interface to receive a read-modify-write command, having an associated read address indicating a location in the memory bank and to either access read data from the location in the memory bank indicated by the read address after an adjustable delay period transpires from a time at which the read-modify-write command was received or to overlap multiple read-modify-write commands. The memory component further includes a data interface to receive write data associated with the read-modify-write command and an error correction circuit to merge the received write data with the read data to form a merged data and write the merged data to the location in the memory bank indicated by the read address.
