Abstract
Methods, systems, and devices for status check using signaling are described. A memory system may receive ready signals from memory dies. The ready signal may indicate whether a memory die is available to receive a command. The memory system may generate an indicator of whether the memory die is available based on values of ready signals. The memory system may output the indicator to a controller over one or more pins based on generating the indicator.
Claims20
An apparatus, comprising:
- a memory device comprising a plurality of memory dies, each memory die of the plurality of memory dies configured to output a ready signal that indicates whether a memory die is available to receive a command;
- an output circuit coupled with each memory die of the plurality of memory dies and configured to receive a plurality of ready signals associated with the plurality of memory dies via a corresponding latch and generate an indicator corresponding to a selected memory die of the plurality of memory dies based at least in part on receiving the plurality of ready signals;
- and
- a first pin coupled with the output circuit and configured to output the indicator to a controller over an input/output (I/O) channel.

An apparatus, comprising:
- a memory device comprising a plurality of memory dies, each memory die of the plurality of memory dies configured to output a ready signal that indicates whether a memory die is available to receive a command;
- an output circuit coupled with each memory die of the plurality of memory dies and configured to receive a plurality of ready signals associated with the plurality of memory dies and generate an indicator configured to indicate whether the memory die is available based at least in part on values of the plurality of ready signals;
- a plurality of first pins coupled with the output circuit and configured to output a first portion of the indicator to a controller over a first input/output (I/O) channel, wherein the plurality of memory dies comprises 2n memory dies, where n is a number of the plurality of first pins;
- and
- a second pin coupled with the output circuit and configured to output a second portion of the indicator to the controller over a second I/O channel, wherein the second portion of the indicator is configured to indicate whether the controller may access the first portion of the indicator over the first I/O channel.

An apparatus, comprising:
- a memory device;
- and
- a control circuit coupled with the memory device and configured to cause the apparatus to:
- receive a plurality of ready signals from a plurality of memory dies, a ready signal of the plurality of ready signals configured to indicate whether a memory die of the plurality of memory dies is available to receive a command;
- generate an indicator of whether the memory die is available based at least in part on values of the plurality of ready signals;
- and
- output the indicator to a controller, wherein the indicator includes an indication of the memory die of the plurality of memory dies that is available.
