Abstract: Apparatus, systems, and methods to manage high capacity memory devices are described. In one example, a controller comprises logic to receive a write operation comprising payload data, a namespace identifier (ID) and a first extended logical block address (LBA), compute a first system cyclic redundancy check (CRC) using a payload CRC, the namespace ID and the first extended LBA, store the first system CRC in association with the first extended LBA in a local memory, and write the payload data, the first system CRC, and a truncated LBA derived from the first extended LBA to a memory. Other examples are also disclosed and claimed.

Abstract: Technologies for media management for column-based memory systems include a memory controller including an indirection table. The memory controller receives a memory access to a column-addressable memory indicative of a memory row address. The memory controller determines a logical sub-block identifier based on the memory row address and looks up a physical sub-block identifier in the indirection table. The memory controller issues a redirected memory access indicative of the physical sub-block identifier to the column-addressable memory. The memory access may include a column read. The memory controller may perform a media management operation by copying or moving data from a source physical sub-block to a destination physical sub-block. The memory controller updates the indirection table with the destination physical sub-block for the associated logical sub-block identifier. Other embodiments are described and claimed.
