Abstract
A memory control device implements split storage of user-data and metadata components of a compound write data word, outputting the user-data component via a memory control interface for storage within an external memory subsystem while separately storing the metadata component within a metadata cache implemented within the memory control device.

1-25. (canceled)
An integrated-circuit memory control component comprising:
- a memory interface to receive host data from one or more memory ICs in a memory read operation;
- control circuitry to recover a first metadata value that corresponds to the host data, including circuitry to:
- search a metadata cache for the first metadata value,
- retrieve the first metadata value from the metadata cache in response to a metadata cache hit, and
- assign a default metadata value to be the first metadata value in response to a metadata cache miss;
- and
- a host interface to output the host data and the first metadata value to a host component after receiving the host data from the one or more memory ICs and recovering the first metadata value.

A method of operation within a memory control IC (integrated circuit), the method comprising:
- reading host data from one or more memory ICs coupled to the memory control IC;
- recovering a first metadata value that corresponds to the host data, including:
- searching a metadata cache for the first metadata value,
- retrieving the first metadata value from the metadata cache in response to a metadata cache hit, and
- assigning a default metadata value to be the first metadata value in response to a metadata cache miss;
- and
- after reading the host data from the one or more memory ICs and recovering the first metadata value, outputting the host data and the first metadata value to a host component.

An integrated-circuit memory control component comprising:
- means for reading host data from one or more memory ICs coupled to the memory control IC;
- and
- means for recovering a first metadata value that corresponds to the host data, including means for:
- searching a metadata cache for the first metadata value,
- retrieving the first metadata value from the metadata cache in response to a metadata cache hit, and
- assigning a default metadata value to be the first metadata value in response to a metadata cache miss;
- and
- means for outputting the host data and the first metadata value to a host component.
