Abstract
Apparatus and method for writing data directly to multi-level cell (MLC) memory without folding or transferring of the data from single-level cell (SLC) memory to MLC memory are disclosed. A memory device, which includes the SLC memory and MLC memory, receives data from a host device. The memory device programs the data (such as the lower/middle/upper pages) from volatile memory into MLC memory, without transferring data from SLC memory. The memory device also stores part of the data (such as the lower/middle pages) in SLC memory as a backup in case of error. In particular, if the data is not properly programmed into the MLC memory, the data in SLC memory is used to program the data a second time into the MLC memory.
