Abstract:
Embodiments relate to embedded Dynamic Random Access Memory (eDRAM) refresh rates in a high performance cache architecture. An aspect includes receiving a plurality of first signals. A refresh request is transmitted via a refresh requestor to a cache memory at a first refresh rate which includes an interval, including a subset of the first signals. The first refresh rate corresponds to a maximum refresh rate. A refresh counter is reset based on receiving a second signal. The refresh counter is incremented after receiving each of a number of refresh requests. A current count is transmitted from a refresh counter to the refresh requestor based on receiving a third signal. The refresh request is transmitted at a second refresh rate, which is less than the first refresh rate. The refresh request is transmitted based on receiving the current count from the refresh counter and determining that the current count is greater than a refresh threshold.
