Abstract: One embodiment of the present application discloses a memory system using programmable sequencers to manage and/or communicate with non-volatile memory (“NVM”) devices with different specifications. The memory system capable of storing information includes a scheduler, NVM device, and programmable NVM interface (“PNI”). In one aspect, the PNI is a programmable sequencer or includes a programmable sequencer. The scheduler schedules a sequence of events or commands to implement memory access command(s). For instance, the scheduler can issue a scheduler command associated with a memory access in accordance with one or more instructions initiated from a memory controller. The NVM device stores information persistently. The PNI, in one embodiment, is configured to access information in the NVM device based on programmed operation code (“opcode”) stored in an opcode memory.
