Techniques for storing data and tags in different memory arrays

摘要

A memory controller includes logic circuitry to generate a first data address identifying a location in a first external memory array for storing first data, a first tag address identifying a location in a second external memory array for storing a first tag, a second data address identifying a location in the second external memory array for storing second data, and a second tag address identifying a location in the first external memory array for storing a second tag. The memory controller includes an interface that transfers the first data address and the first tag address for a first set of memory operations in the first and the second external memory arrays. The interface transfers the second data address and the second tag address for a second set of memory operations in the first and the second external memory arrays.

1. A memory controller comprising:
logic circuitry to generate:
a first data address identifying a location in a first external memory bank group for storing first data,a first tag address identifying a location in a second external memory bank group for storing a first tag associated with the first data,a second data address identifying a location in the second external memory bank group for storing second data, anda second tag address identifying a location in the first external memory bank group for storing a second tag associated with the second data; and an interface that transfers the first data address and the first tag address for a first set of memory operations in the first external memory bank group and the second external memory bank group, wherein the interface transfers the second data address and the second tag address for a second set of memory operations in the first external memory bank group and the second external memory bank group.
