Apparatus and method for multi-mode storage

摘要

According to an example, multi-mode storage may include operating a first array including a first memory and a second array including a second memory in one or more modes of operation. The first memory may be a relatively denser memory compared to the second memory and the second memory may be a relatively faster memory compared to the first memory. The modes of operation may include a first mode of operation where the first array functions as the relatively denser memory compared to the second memory and the second array functions as the relatively faster memory compared to the first memory, a second mode of operation where the second array is operated as an automatic cache of a portion of a dataset, and a third mode of operation where a cache-tag functionality used to support the second mode of operation is instead used to provide a CAM.

1. A method for multi-mode storage, the method comprising:
operating, by a processor, a first array including a first memory and a second array including a second memory in at least one of a plurality of modes of operation, wherein the first memory is a relatively denser memory compared to the second memory and the second memory is a relatively faster memory compared to the first memory, the modes of operation comprising:
a first mode of operation where the first array functions as the relatively denser memory compared to the second memory and the second array functions as the relatively faster memory compared to the first memory,a second mode of operation where the second array is operated as an automatic cache of a portion of a dataset, anda third mode of operation where a cache-tag functionality used to support the second mode of operation is instead used to provide a content-addressable memory (CAM).
