Samsung patents memory chip design that reports status before sending data
This filing describes a nonvolatile memory device where each chip has specific pads to report the status of its internal storage sections. Instead of sending data immediately, the chip first outputs status signals to show which sections are ready, then sends the data based on that information.
In the filing’s own words
A nonvolatile memory device includes a plurality of memory chips. Each of the plurality of memory chips may include a memory cell array including a plurality of planes and configured to store data, a command-address pad configured to receive a status output start command and an output command, at least one status output pad configured to sequentially output status signals, respectively corresponding to operating statuses of the plurality of planes, based on the status output start command, and an input/output pad configured to sequentially output at least a portion of data stored in the plurality of planes based on the status signal and the output command.
What exactly they claim (claim 1)
1. A nonvolatile memory device comprising: a plurality of memory chips, wherein: each of the plurality of memory chips comprises: a memory cell array comprising a plurality of planes and configured to store data; a command-address pad configured to receive a status output start command and an output command; at least one status output pad configured to sequentially output status signals, respectively corresponding to operating statuses of the plurality of planes, based on the status output start command; and an input/output pad configured to sequentially output at least a portion of data stored in the plurality of planes based on the status signal and the output command.
