Abstract: In a Multi Level Cell (MLC) memory array, a burst of data from a host may be written in only lower pages of a block in a rapid manner. Other data from a host may be written in lower and upper pages so that data is more efficiently arranged for long term storage.

Abstract: The present invention present methods and architectures for the pipelining of read operation with write operations. In particular, methods are presented for pipelining data relocation operations that allow for the checking and correction of data in the controller prior to its being re-written, but diminish or eliminate the additional time penalty this would normally incur. A number of architectural improve are described to facilitate these methods, including: introducing two registers on the memory where each is independently accessible by the controller; allowing a first memory register to be written from while a second register is written to; introducing two registers on the memory where the contents of the registers can be swapped.

Abstract: A die assignment scheme assigns data, in the order it is received, to multiple memory dies with some randomness. Randomization events, such as skipping dies or reversing direction, occur at intervals, with a deterministic assignment scheme used between randomization events. Intervals between randomization events may be of random length, or of fixed length.

Abstract: A die assignment scheme assigns data in the order it is received, to multiple memory dies. Any busy dies are skipped until they become ready again so that the system does not wait for busy dies to become ready. Immediately sequential writes to the same die are prohibited so that reading speed is not impacted.
