System and methods for dram-less garbage collection with improved performance

A method, comprising:

• receiving, by processing circuitry of a memory device, a garbage collection request associated with a destination memory block of a system memory of the memory device, and in response to the garbage collection request:
• determining, by the processing circuitry, whether a memory block size of the system memory is greater than a volatile memory size of volatile memory of the memory device,
• pausing, by the processing circuitry, data change operations queued by the processing circuitry, but allowing for read operations and error handling operations to continue,
• while data change operations are paused and read operations are allowed to continue:
• loading, by the processing circuitry, a first portion of data associated with a source memory block of the system memory to a first volatile memory of the volatile memory,
• loading, by the processing circuitry, a second portion of data associated with the source memory block to a second volatile memory of the volatile memory, and
• writing, by the processing circuitry, each of the first portion of data from the first volatile memory and the second portion of data from the second volatile memory to the destination memory block to complete garbage collection, and
• unpausing, by the processing circuitry, the data change operations.

A non-transitory computer-readable medium having non-transitory computer-readable instructions encoded thereon that, when executed performs a method comprising receiving a garbage collection request associated with a destination memory block of a system memory, and in response to the garbage collection request:

• determining whether a memory block size of the system memory is greater than a volatile memory size of volatile memory,
• pausing data change operations which are queued, but allowing for read operations and error handling operations to continue,
• while data change operations are paused and read operations are allowed to continue:
• loading a first portion of data associated with a source memory block of the system memory to a first volatile memory of the volatile memory,
• loading a second portion of data associated with the source memory block to a second volatile memory of the volatile memory, and
• writing each of the first portion of data from the first volatile memory and the second portion of data from the second volatile memory to the destination memory block to complete garbage collection, and
• unpausing the data change operations.
