Circuits and methods for utilizing multiple programmable memory using one-time programmable (OTP) memory in a fan controller. The fan controller generally includes a plurality of OTP memories, each capable of being programmed once and only once; a state machine configured to enable writing updated parameter information to an available OTP memory and to provide a control signal indicating a next OTP memory to which next received data are to be written, and read logic coupled to the plurality of OTP memories, the read logic configured to read an output from a most recently programmed OTP memory. The method generally includes receiving updated parameter information to be stored in the memory, programming one of a plurality of one-time programmable (OTP) memories with the updated parameter information, indicating an availability of a next OTP memory, and reading an output from a most recently programmed OTP memory.
