The invention provides a key value data stock internal calculation framework based on a ReRAM. The framework comprises a memory component, a ReRAM component and a disk component, the memory component is at least configured to contain the random key value pairs into a sequential batch write operation; the ReRAM component comprises a storage module and a calculation module; the storage module at least comprises a highest layer, a secondary higher layer and a WAL file of the LSM-tree; the calculation module is at least configured to adopt a merging accelerator engine to process the highest-layer and secondary-layer merging tasks; a disk component at least configured to: perform a low-level merge operation; for a write request, firstly recording a key value pair in a WAL file, and storing the key value pair in a memory table according to a key range of the key value pair, and for a read request, accessing the ReRAM component when the highest layer and the secondary layer are read; according to the method, the wri
