APPARATUSES AND METHODS FOR DATA MANAGEMENT IN A MEMORY DEVICE

Abstract:

In some examples, a system may include a plurality of memory blocks, a first data bus coupled to the plurality of memory blocks in a memory device, a second data bus coupled to the plurality of memory blocks, a controller configured to perform memory read and write operations on the plurality of memory blocks via the first data bus, and a non-volatile storage (NVS) data transfer circuit configured to transfer data in a first memory block of the plurality of memory blocks to a NVS device via the second data bus. The first memory block may be a cold data block least accessed among the plurality of memory blocks. The cold data transfer may be performed via the second data bus when a different memory block is being accessed via the first data bus concurrently. The second data bus may be a fuse bus in the memory device.
