1. An electronic system comprising:
a host configured to output a program request, a logical address, and data; and
a memory system configured to map the logical address to a first physical address, program the data to first memory blocks corresponding to the first physical address in a single level cell (SLC) method, map the logical address from the first physical address to a second physical address, migrate the data stored in the first memory blocks to a second memory block corresponding to the second physical address in a higher level cell method than the SLC method, and transmit the second physical address to the host,
wherein the host outputs a read request for acquiring the data and the second physical address to the memory system, and
wherein the memory system, in response to the read request, selects the second memory block stored in the data corresponding to the read request based on the second physical address received from the host, and provides the data read from the second memory block to the host.
