Abstract
A system and method is disclosed for managing data in a garbage collection operation using a hybrid push-pull technique. The system includes multiple non-volatile memory sub-drives associated with a specific data type and shared volatile memory garbage collection buffer sized to only receive a predetermined amount of host data of a single data type and associated large data chunk correction data. A controller identifies and accumulates valid data of a single data type from the source block and combines it with XOR data for that valid data to generate a protected data stripe in the buffer. The controller writes the protected data stripe to the sub-drive containing data of the same data type. Only after writing the protected data stripe to the appropriate sub-drive, the controller repeats the process in the same source block for the same or different data type of data.
