Enhanced IO interface for plc program and program-suspend-resume operations

A method, comprising:

• at a NAND memory device comprising a first portion memory comprising blocks of single-level cell (SLC) memory and a second portion of memory comprising blocks of multi-level cell (MLC) memory storing n bits per cell, wherein n is 3 or more:
• copying data from a set of n SLC pages in a block of SLC memory into n respective page buffer latches, wherein the set of n SLC pages of the block of SLC memory has a set of sequentially ordered page addresses;
• and
• copying data from the n respective page buffer latches to an MLC page in a block of MLC memory.

A system, comprising:

• a host, having a first input-output (IO) interface;
• a NAND device having a second IO interface coupled to the first IO interface, the NAND device further including,
• a first portion memory comprising blocks of single-level cell (SLC) memory;
• a second portion of memory comprising blocks of penta-level cell (PLC) memory;
• a plurality of page buffer latches;
• and
• logic to:
• copy data from a set of five SLC pages in a block of SLC memory into five respective page buffer latches;
• and
• copy data from the five respective page buffer latches to a PLC page in a block of PLC memory.
