Cache data processing method and device, equipment and storage medium

The invention provides a cache data processing method and device, equipment and a storage medium. Relates to the technical field of computers. The method comprises the following steps: when a superior unit triggers a write operation of a target cache line, if the target cache line does not exist in a cache, applying for an idle cache line; writing one or more target data bits into the idle cache line according to the write operation to obtain a first cache line; when the superior unit triggers the read operation of the target cache line, obtaining the target cache line in the memory; according to the target data bit written in the first cache line, merging with the target cache line to obtain a second cache line; and feeding back the second cache line to the superior unit. The target cache line in the memory does not need to be read in the write operation process. And when the read operation is executed, merging the target cache line in the memory with the first cache line to obtain a second cache line. And t
