  • Patent number: 11803321
    Abstract: A method can include receiving, by a first controller component of a memory sub-system, a read operation, responsive to receiving the read operation, interrupting, by the first controller component, one or more program operations being performed by the memory sub-system, receiving, by the first controller component, a control sequence from a second controller component, wherein the control sequence is based on context data associated with the interrupted one or more program operations, and performing, by the first controller component, the control sequence by copying data of the interrupted one or more program operations from a first memory location to a second memory location of a memory component associated with the memory sub-system, and performing the read operation.

  • Publication number: 20230059543
    Abstract: A memory device includes a memory array comprising a plurality of memory planes, wherein the plurality of memory planes are arranged in a plurality of independent plane groups, and wherein each of the plurality of independent plane groups comprises one or more of the plurality of memory planes. The memory device further includes a plurality of independent analog driver circuits coupled to the memory array, wherein a respective one of the plurality of independent analog driver circuits is associated with a respective one of the plurality of independent plane groups. The memory device further includes a common analog circuit coupled to the memory array, wherein the common analog circuit is shared by the plurality of independent analog driver circuits and the plurality of independent plane groups.

  • Publication number: 20230014869
    Abstract: A method can include receiving, by a first controller component of a memory sub-system, a read operation, responsive to receiving the read operation, interrupting, by the first controller component, one or more program operations being performed by the memory sub-system, receiving, by the first controller component, a control sequence from a second controller component, wherein the control sequence is based on context data associated with the interrupted one or more program operations, and performing, by the first controller component, the control sequence by copying data of the interrupted one or more program operations from a first memory location to a second memory location of a memory component associated with the memory sub-system, and performing the read operation.

  • Patent number: 11442656
    Abstract: An indication that one or more program operations have been interrupted as a result of a read operation can be received at a first controller component associated with a memory sub-system. Context data associated with interrupted program operations can be received at the first controller component. A control sequence based on the context data can be generated at the first controller component. The control sequence can indicate how a second controller component associated with the memory sub-system interacts with a memory component of the memory sub-system to perform the read operation and to resume the interrupted program operations. The control sequence can further specify one or more additional operations that are associated with copying data of the interrupted program operations between first and second memory locations of the memory component. The control sequence can be provided to the second controller component.

  • Patent number: 10929056
    Abstract: A read operation can be received while one or more program operations are being performed at a memory sub-system. In response to receiving the read operation, the one or more program operations being performed at the memory sub-system can be interrupted. Context data associated with the one or more interrupted program operations can be determined and the context data can be provided to a firmware associated with the memory sub-system. A control sequence can be received from the firmware based on the context data. The read operation can be performed and the one or more interrupted program operations can be resumed based on the control sequence from the firmware.

  • Publication number: 20170046102
    Abstract: A memory channel command interface for one or more memory channels includes, for each memory channel, programmable storage for memory commands, a single channel processor for executing the memory commands, and a task engine for communicating output of the single channel processor to a memory medium. The memory commands may be organized into jobs including operations that include tasks. The tasks may be stored as part of operations in an operation memory, or may be stored in a task memory with pointers to the tasks being stored as part of operations in the operation memory. The memory channel command interface may further include a memory medium status storage that stores a priority indication for a memory command, based on a condition other than order of arrival or receipt of the memory command, and the single channel processor controls order of execution of memory commands based on the priority indication.
