Use of a direct data file system with a continuous logical address space interface and control of file address storage in logical blocks

A method of a host system transferring data of file objects through an interface adapted for connection with a non-volatile memory system of a type having blocks of memory cells that are erasable together prior to being reprogrammed, comprising:

• maintaining at the interface a logical address space that is divided into logical blocks, and
• designating addresses of data within individual ones of the file objects within one or more of the logical blocks in a manner that the logical blocks may individually contain addresses of more than one file object but which limits to less than at least one preset limit a number of logical blocks that are only partially filled with an address of an individual file object such that an address of one or more other file objects are or may be written into the partially filled blocks.

A method of storing data of file objects in a non-volatile memory system having blocks of memory cells that are erasable together prior to being re-programmed with the data, wherein:

• a logical address space is divided into logical blocks that individually have at least one characteristic corresponding to that of the individual memory cell blocks,
• assigning addresses of data of individual file objects within one or more of the logical blocks, wherein the logical blocks may individually contain addresses of data of more than one file object but the number of logical blocks containing an address of a particular individual file object plus an address of another file object is limited, and
• addresses of the logical blocks are mapped within the memory system to addresses of memory cell blocks.
