Abstract
In one embodiment, a method includes: in response to a sub-cacheline memory access request, receiving a data-line from a memory coupled to a processor; receiving tag information included in metadata associated with the data-line from the memory; determining, in a memory controller, whether a first tag identifier of the tag information matches a tag portion of an address of the memory line associated with the sub-cacheline memory access request, and in response to determining a match, storing a first portion of the data-line associated with the first tag identifier in a cache line of a cache of the processor, the first portion a sub-cacheline width. This method allows data lines stored in memory associated with multiple different tag metadata to be divided into multiple cachelines comprising the sub-cacheline data associated with a particular metadata address tag. Other embodiments are described and claimed.
