A Flash memory array comprises a plurality of Erase Sectors (Esecs) arranged in a plurality of Erase Sector Groups (ESGs), Physical Pages (slices), and Physical Sectors (PSecs), and there is a non-binary number of at least one of the Erase Sector Groups (ESGs), Physical Pages (slices), and Physical Sectors (PSecs). A user address is translated into a physical address using modular arithmetic to determine pointers (ysel, esg, psec) for specifying a given Erase Sector (ESec) within a given Erase Sector Group (ESG); a given Erase Sector Group (ESG) within a given Physical Sector (Psec); and a given Physical Sector (PSec) within the array.

Non binary flash array architecture and method of operation

A multi-level cell (MLC) memory array may be programmed using a programming circuit having a binary input register to store data to be input into the MLC array and a register to store a programming vector, where each element in the programming vector corresponds to a charge storage region of an MLC in the array. A controller may map pairs of bits from the input register to elements in the programming vector, such that mapping a pair of bits to an element of the programming vector may set the vector element to a 'program' value if the pair of bits corresponds to at least one specific program state associated with the programming vector.
