Managing multiple cache memory circuit operations

A method, comprising:

• sending, by a second-level cache memory circuit, a plurality of probe requests regarding a particular cache line to a plurality of first-level cache memory circuits in response to receiving an acquire request for the particular cache line from a particular first-level cache memory circuit of plurality of first-level cache memory circuits;
• in response to determining that a different first-level cache memory circuit of the plurality of first-level cache memory circuits is evicting a local copy of the particular cache line:
• receiving the local copy of the particular cache line from the different first-level cache memory circuit,
• writing the local copy of the particular cache line to a higher-level memory circuit;
• sending a prefetch request for a new copy of the particular cache line to the higher-level memory circuit while the different first-level cache memory circuit responds to a corresponding one of the plurality of probe requests;
• selecting, by a control circuit included in the second-level cache memory circuit, a particular bank of a plurality of banks included in the second-level cache memory circuit;
• and
• transferring, by the particular bank, the acquire request from an input queue circuit to an initial pipeline stage of a plurality of pipeline stages included in the particular bank based on a length of time since the acquire request was received.

An apparatus, comprising:

• a plurality of bank circuits including a first bank circuit that includes a first input queue circuit, a plurality of first pipeline stages, and a first storage circuit,
• a control circuit configured to:
• receive a plurality of requests from a plurality of lower-level cache memory circuits;
• select the first bank circuit;
• and
• store a first request of the plurality of requests in the first input queue circuit;
• and
• wherein the first input queue circuit is configured to transfer the first request to a first initial pipeline stage of the plurality of first pipeline stages based on a first duration since the first request was received.
