Abstract
The present disclosure describes aspects of free block address management for compressed data storage. In various aspects, a memory controller maintains addresses of free blocks of a memory through a linked list of address storage blocks stored in the memory. An address storage block may include addresses of the free blocks of the memory and an address to a next address storage block of the linked list (e.g., block freelist). As the memory controller writes data to the free blocks of the memory and consumes the addresses stored in the address storage blocks, the memory controller can release the address storage blocks as free blocks. When the free blocks and associated addresses are used up, the remaining address storage blocks are released, and no memory is needed to maintain the list of free blocks. By so doing, the described aspects can reduce free block management overheard and improve memory efficiency.
