Abstract
Systems and methods are provided for acquiring status information from a plurality of memory die. An apparatus is provided that includes a plurality of memory die and a memory controller. The memory controller is configured to broadcast a first status command to the plurality of memory die, receive a first status response concurrently from the plurality of memory die based on the first status command, and send a repair command to one or more of the plurality of memory die in response to the first status response not satisfying first predetermined status criteria.
Claims20
An apparatus comprising:
- a plurality of memory die;
- and
- a memory controller configured to:
- broadcast a first status command to the plurality of memory die;
- receive a first status response concurrently from the plurality of memory die based on the first status command;
- and
- send a repair command to one or more of the plurality of memory die in response to the first status response not satisfying first predetermined status criteria.
A system comprising:
- a plurality of memory die;
- a shared I/O bus coupled to each of the plurality of memory die;
- and
- a memory controller configured to:
- transmit a first status command over the shared I/O bus to each of the plurality of memory die;
- receive one bit of status information concurrently from each of the plurality of memory die based on the first status command, the received bits comprising a first status response;
- and
- send a repair command to a memory die that failed to respond to the first status command.
A method comprising:
- broadcasting a first status command to a plurality of memory die, each of the plurality of memory die configured to ignore the first status command in response to experiencing a predetermined unwanted event;
- receiving a first status response concurrently from the plurality of memory die based on the first status command;
- and
- sending a memory operation command to one or more of the plurality of memory die in response to the first status response satisfying first predetermined status criteria.
An apparatus comprising:
- a plurality of memory die;
- and
- a memory controller means configured to:
- broadcast a first status command to the plurality of memory die;
- receive a first status response concurrently from the plurality of memory die based on the first status command;
- and
- send a repair command to one or more of the plurality of memory die in response to the first status response not satisfying first predetermined status criteria.
