A portion of a nonvolatile memory is partitioned from a main multi-level memory array to operate as a cache. The cache memory is configured to store at less capacity per memory cell and finer granularity of write units compared to the main memory. In a block-oriented memory architecture, the cache has multiple functions, not merely to improve access speed, but is an integral part of a sequential update block system. Decisions to write data to the cache memory or directly to the main memory depend on the attributes and characteristics of the data to be written, the state of the blocks in the main memory portion and the state of the blocks in the cache portion.

In a memory array having a minimum unit of erase of a block, a scratch pad block is used to store data that is later written to another block. The data may be written to the scratch pad block with a low degree of parallelism and later written to another location with a high degree of parallelism so that it is stored with high density. Data may be temporarily stored in the scratch pad block until it can be more efficiently stored elsewhere. This may be when some other data is received. Unrelated data may be stored in the same page of a scratch pad block.
