  • Publication number: 20230013757
    Abstract: A processing device in a memory system identifies, while the memory device is in a first state condition, a plurality of workload conditions associated with the memory device, wherein the plurality of workload conditions comprise data reflecting a performance condition of the memory device. The processing device determines, while the memory device is in the first state condition, a host rate of a host system write performance for the memory device based on one or more workload conditions of the plurality of workload conditions. The processing device determines that one or more workload conditions of the plurality of workload conditions satisfies a first threshold criterion. Responsive to determining that the one or more workload conditions of the plurality of workload conditions satisfies the first threshold criterion, the processing device detects a change in a condition of the memory device from the first state to a second state.

  • Patent number: 11513959
    Abstract: A request to read data from a location associated with a memory component is received. The request is assigned a first tag, the first tag having a first identifier of a first buffer to store data read from the location. The request to read data is determined to collide with an earlier request to write data to the location. The earlier request is assigned a second tag, the second tag having a second identifier of a second buffer to store data to write to the location. An attempt to lock the second tag and the second buffer for the request to read data is made. The request to read data is fulfilled from the second buffer in response to a successful attempt to lock the second tag and the second buffer.

  • Patent number: 11481348
    Abstract: A first operation identifier is assigned to a current operation directed to a memory component, the first operation identifier having a first entry in a first data structure that associates the first operation identifier with a first buffer identifier. It is determined whether the current operation collides with a prior operation assigned a second operation identifier, the second operation identifier having a second entry in the first data structure that associates the second operation identifier with a second buffer identifier. A latest flag is updated to indicate that the first entry is a latest operation directed to an address (1) in response to determining that the current operation collides with the prior operation and that the current and prior operations are read operations, or (2) in response to determining to determining that the current operation does not collide with a prior operation.

  • Publication number: 20220171574
    Abstract: A memory sub-system having memory cells formed on a plurality of integrated circuit dies. After receiving a command from a host system to store data, the memory sub-system queues the command to allocate pages of memory cells in a plurality of dies in the plurality of integrated circuit dies based on a determination that each of the plurality of dies is available to perform a data programming operation for the command. Based on the page application, the memory sub-system generates a portion of a media layout to at least map logical addresses of the data identified in the command to the allocated pages and receives the data from the host system. The memory sub-system stores the data into the pages using a multi-pass programming technique, where an atomic multi-pass programming operation can be configured to use at least two pages in separate planes in one or more dies in the plurality of integrated circuit dies to program at least a portion of the data.

  • Publication number: 20220083276
    Abstract: A memory sub-system configured to dynamically determine input/output sizes of write commands based on a media physical layout of a memory sub-system. The memory sub-system can identify, dynamically in response to write commands being selected for execution in media units of the memory sub-system, a portion of a media layout that maps from logical addresses identified by the write commands in the logical address space to physical addresses of memory units in the media units. Based on the media layout, an input/output size for a next write command is identified and transmitted to the host system in a response. The host system generates the next write command and configures the amount of data to be written through the next write command based on based on the input/output size identified in the response.

  • Patent number: 11249896
    Abstract: A system includes integrated circuit (IC) dies having memory cells and a processing device coupled to the IC dies. The processing device performs operations including storing, within a zone map data structure, zones of a logical block address (LBA) space sequentially mapped to physical address space of the IC dies. A zone map entry in the zone map data structure corresponds to a data group written to one or more of the IC dies. The operations further include storing, within a block set data structure indexed by a block set identifier of the zone map entry, a die identifier and a block identifier for each data block of multiple data blocks of the data group, and writing multiple data groups, which are sequentially mapped across the zones, sequentially across the IC dies. Each data block can correspond to a media (or erase) block of the IC dies.
