Abstract
Concurrent refresh in a cache memory includes calculating a refresh time interval at a centralized refresh controller, the centralized refresh controller being common to all cache memory banks of the cache memory, transmitting a starting time of the refresh time interval to a bank controller, the bank controller being local to, and associated with, only one cache memory bank of the cache memory, sampling a continuous refresh status indicative of a number of refreshes necessary to maintain data within the cache memory bank associated with the bank controller, requesting a gap in a processing pipeline of the cache memory to facilitate the number of refreshes necessary, receiving a refresh grant in response to the requesting, and transmitting an encoded refresh command to the bank controller, the encoded refresh command indicating a number of refresh operations granted to the cache memory bank associated with the bank controller.
