ELECTRONIC SYSTEM WITH MEMORY DEVICE

PROBLEM TO BE SOLVED: To provide an electronic system with hybrid memory devices utilizing single level and multi level memory cells.SOLUTION: Logical addresses are distributed between single level 214 and multilevel 206 memory cells on the basis of a frequency 210 of write operations performed, and the like. Initial storage of data corresponding to a logical address in memory can be determined by various methods including initially writing all data to single level memory or initially writing all data to multilevel memory, and the like. In other methods, a host directs writes of data to logical address to be performed to single level or multilevel memory cells on the basis of anticipated usage.
