  • Patent number: 11675696
    Abstract: A value setting associated with one or more parameters of a host-side interface and a memory-side interface of an input/output (I/O) expander is configured to enable Open NAND Flash Interface (ONFI)-compliant communications between a host system and a target memory die of a memory sub-system. The I/O expander processes one or more ONFI-compliant communications between the host system and the target memory die, wherein the one or more ONFI-compliant communications relate to execution of a memory access operation.
    Type: Grant
    Filed: September 14, 2021
    Date of Patent: June 13, 2023
    Assignee: Micron Technology, Inc.

  • Patent number: 11132292
    Abstract: A read command to read a target memory die of a memory sub-system is received from a host system via a host-side interface of an active input/output (I/O) expander. The active I/O expander identifies a page address corresponding to the target memory die and decodes the read command to send to a memory stack associated with the page address corresponding to the target memory die. Read data is received via a memory-side interface of the active I/O expander from the memory stack including the target memory die. A signal conditioning operation is performed on the read data to generate conditioned read data. The active I/O expander sends, via the host-side interface, the conditioned read data to the host system.

  • Patent number: 9524118
    Abstract: Systems, devices, memory controllers, and methods for controlling memory are described. One such method includes activating a memory unit of a memory device; after activating the memory unit, providing a command to the memory device; and returning the memory unit to a previous state if the command does not indicate a target memory volume, wherein the memory unit remains active if the command indicates a target memory volume associated with the memory unit.
