The invention discloses a multi-layer
memory management method and device, a storage medium and
electronic equipment, and relates to the technical field of
memory management, and the method comprises the steps that a prediction frequency set of storage equipment is obtained through prediction by using a reference information set corresponding to the storage equipment, and the storage equipment comprises a first memory and a second memory; the first
delay of the first memory is smaller than the second
delay of the second memory; determining a plurality of target sub-data contained in the target data of the storage device, and determining predicted access frequencies corresponding to the plurality of target sub-data based on the predicted frequency set; under the condition that the predicted access frequencies corresponding to the multiple pieces of target sub-data meet a preset splitting condition, splitting the target data into multiple pieces of target sub-data; and storing the target sub-data with the predicted
access frequency greater than the frequency threshold in the first memory, and storing the target sub-data with the predicted
access frequency less than the frequency threshold in the second memory. The technical problem that a
memory management method in the related technology is low in
resource utilization rate is solved.
