Abstract
Technology is disclosed for relocating data in a non-volatile storage system. An integrated memory assembly has a control die and a memory die that contains the memory cells. The control die contains control circuitry that relocates data from one set of physical addresses on the memory die to another set of physical addresses on the memory die. This relocation results in a change of a mapping between logical addresses for the data and the physical addresses for the data. The control circuitry may update an L2P table on the memory die after the relocation to map the logical addresses of the data to the second set of physical addresses. The control die may construct a validity bitmap, which specifies whether data at a physical address is valid or invalid. The foregoing reduces data transfer between the integrated memory assembly and a memory controller, which saves time and power.
