US 2019/0171389 A1 · STREAMED PROGRAM COMMANDS WITH PERIODIC GARBAGE COLLECTION

Abstract

Apparatuses, systems, methods, and computer program products for streamed program commands with periodic garbage collection are disclosed. A controller is configured to set up a data path between the controller and a memory device to initialize an open mode. A controller is configured to perform a plurality of program operations on a memory device in an open mode using a same set up data path. A controller is configured to, in response to exiting an open mode, perform a garbage collection operation on a memory device.

Claims20

Dependent claims

An apparatus comprising:

a controller for a memory device, the controller configured to:
set up a data path between the controller and the memory device to initialize an open mode;
perform a plurality of program operations on the memory device in the open mode using the same set up data path;
and
in response to exiting the open mode, perform a garbage collection operation on the memory device.

2 more elements

A system comprising:

a memory device, comprising:
a memory array of memory elements;
and
a set of memory latches for the memory array;
and
a controller including a controller memory, the controller in communication with a host computing device and configured to:
receive memory commands including program data from the host computing device;
transmit the program data to one or more memory latches of the set of memory latches in a streaming write mode;
and
in response to detecting one or more trigger events:
exit the streaming write mode;
and
in response to exiting the streaming write mode, perform a garbage collection operation on the memory array.
