Abstract
A device, method, and a data storage medium, configured to enhance an item access bandwidth and atomic operation are provided. The device comprises: a comparison module, a cache, and a distribution module; wherein the comparison module is configured to receive a query request from a service side, determine whether an address pointed to by the query request and an item address stored in the cache are identical. If so, and a valid identifier vld is valid, the comparison module is configured to directly return the item data stored in the cache to the service side without initiating a request for looking up an off-chip memory, so as to reduce a frequency of accessing the off-chip memory. If not, the comparison module is configured to initiate a request for looking up the off-chip memory, so as to process, according to a first preconfigured rule, item data returned by the off-chip memory.
