Independent Sense Amplifier Addressing And Quota Sharing In Non-Volatile Memory
Abstract:
Independent sense amplifier addressing provides separate column addresses to individual sense amplifier groups within a single bay during one column address cycle. A memory system determines whether the individual memory cells or bits of a column at a bay can be skipped. For each sense amplifier group having at least one memory cell (or bit) that needs to be programmed, the system determines for the first column address whether the memory cell can be skipped. If a bit or memory cell having a first column address from the sense amplifier group can be skipped, the system determines a next bit having a column address from the group that needs to be programmed. The system groups the next column address for programming during the first column address cycle. The system can program a different column address for different sense amplifier groups within the bay during a single column address cycle.
