A system and related method, including system memory with a source memory block and a destination memory block each of a memory block size, a first volatile memory and a second volatile memory, each of a volatile memory size. The system includes processing circuitry to receive a garbage collection request associated with the destination memory block. The processing circuitry then determines whether the memory block size is greater than the volatile memory size and pauses data change operations but allows for passive operations to continue. While data change operations are paused the processing circuitry loads a first portion of data of the source memory block to the first volatile memory and a second portion of the data to the second volatile memory. The processing circuitry writes each portion of data from the volatile memory to the destination memory block to complete garbage collection and unpauses the data change operations.

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

A system and related method, the system including control circuitry and memory with a first memory block of a first memory density and a second memory block of a second memory density which is greater than the first memory density. Control circuitry, which is communicatively coupled to the memory, is configured to determine to transfer data from the first memory block to the second memory block, generate parity data based on the data and cause to store the parity data at a parity address corresponding to an available portion of the first memory block. Control circuitry is further to cause to update a look-up table with the parity data address and cause to copy the data from the first memory block to the second memory block.
