PERIODIC FLUSH IN MEMORY COMPONENT THAT IS USING GREEDY GARBAGE COLLECTION

Abstract:

A method includes identifying a first block of a plurality of blocks stored at a first memory based on an amount of valid data of the first block, and writing the valid data of the first block from the first memory to a second memory. The first memory has a first memory type and the second memory has a second memory type different from the first memory type. The method further includes identifying a second block of the plurality of blocks stored at the first memory based on an age of valid data of the second block, determining that the age of the valid data of the second block satisfies a threshold condition, and in response to determining that the age of the valid data of the second block satisfies the threshold condition, writing the valid data of the second block from the first memory to the second memory.
