Silent cache line eviction

A method comprising:

• receiving, at a memory device, a memory operation from a host, the memory operation establishing data and metadata in a cache line of the memory device, wherein the metadata is cache coherency metadata;
• storing the metadata in a memory element that corresponds to the cache line;
• identifying an eviction trigger to evict the cache line;
• comparing, in response to the eviction trigger, current metadata of the cache line with the metadata in the memory element to determine whether the metadata has changed;
• and
• evicting the cache line without writing the metadata to backing memory in response to the metadata being unchanged.

A non-transitory machine readable medium including instructions that, when executed by processing circuitry, cause the processing circuitry to perform operations comprising:

• receiving, at a memory device, a memory operation from a host, the memory operation establishing data and metadata in a cache line of the memory device, wherein the metadata is cache coherency metadata;
• storing the metadata in a memory element that corresponds to the cache line;
• identifying an eviction trigger to evict the cache line;
• comparing, in response to the eviction trigger, current metadata of the cache line with the metadata in the memory element to determine whether the metadata has changed;
• and
• evicting the cache line without writing the metadata to backing memory in response to the metadata being unchanged.
