发明名称 AUXILIARY PARITY BITS FOR DATA WRITTEN IN MULTI-LEVEL CELLS
摘要 Methods of writing data to and reading data from memory devices and systems for writing and reading data are disclosed. In a particular embodiment, a method includes writing data bits a first time into a memory. Auxiliary parity bits are written in the memory, where the auxiliary parity bits are computed based on the data bits. Subsequent to writing the data bits a first time and writing the auxiliary parity bits, the data bits are written a second time into the memory. Writing the data bits the first time and writing the data bits the second time are directed to one or more storage elements at a common physical address in the memory. Subsequent to writing the data bits the second time, the auxiliary parity bits are discarded while maintaining the data bits in the memory.
