Abstract

An electronic system and method of operation thereof includes: a control unit for receiving a patterned signal; a recognizer module, coupled to the control unit, for recognizing an unique trigger from the patterned signal; an operation module, coupled to the recognizer module, for detecting an operational mode from the unique trigger; and a change module, coupled to the operation module, for configuring a system state change of a memory sub-system based on the operational mode.

Claims

1. A method of operation of an electronic system comprising:

receiving a patterned signal, wherein the patterned signal includes a plurality of unique triggers;

recognizing a first unique trigger from the plurality of unique triggers in the patterned signal, each unique trigger within the plurality of unique triggers corresponding to a distinct operational mode;

in response to recognizing the first unique trigger, selecting a first operational mode for a memory sub-system of the electronic system, wherein the first operational mode is a firmware update mode;

configuring a first system state change of the memory sub-system based on the first unique trigger;

recognizing a second unique trigger from the plurality of unique triggers in the patterned signal; and

in response to recognizing the second unique trigger, selecting a second operational mode for the memory sub-system.

2. The method as claimed in claim 1 wherein recognizing the first unique trigger includes recognizing an update signal for updating a firmware of the memory sub-system.

3. The method as claimed in claim 1 wherein recognizing the second unique trigger includes recognizing a version signal for a reversion of a firmware of the memory sub-system.

4. The method as claimed in claim 1 wherein recognizing the second unique trigger includes recognizing a security signal for toggling a security mode of the memory sub-system.

5. The method as claimed in claim 1 wherein recognizing the second unique trigger includes recognizing a manufacturing signal for toggling a manufacturing mode of the memory sub-system.

6. The method as claimed in claim 1 wherein the memory sub-system includes a non-volatile memory array and a memory controller for managing the non-volatile memory array.

7. The method of claim 1, wherein receiving the patterned signal includes accepting the patterned signal in accordance with a determination that the patterned signal was received during an available period for accepting patterned signals.

8. The method of claim 1, wherein receiving the patterned signal comprises monitoring the patterned signal with a signal envelope follower and wherein recognizing the first unique trigger comprises monitoring the first unique trigger with a trigger envelope follower distinct from the signal envelope follower.

9. The method of claim 1, wherein the patterned signal further includes a speed negotiation signal, and wherein recognizing the first unique trigger comprises distinguishing the first unique trigger from the speed negotiation signal.

10. An electronic system comprising:

a control unit for receiving a patterned signal, wherein the patterned signal includes a plurality of unique triggers;

a recognizer module, coupled to the control unit, for recognizing a first unique trigger from the plurality of unique triggers in the patterned signal, each unique trigger within the plurality of unique triggers corresponding to a distinct operational mode;

an operation module, coupled to the recognizer module, for in response to recognizing the first unique trigger, selecting a first operational mode for a memory sub-system of the electronic system, wherein the first operational mode a firmware update mode; and

a change module, coupled to the operation module, for configuring a first system state change of the memory sub-system based on the first unique trigger;

recognizing, by the recognizer module, a second unique trigger from the plurality of unique triggers in the patterned signal; and

in response to recognizing the second unique trigger, selecting, by the operation module, a second operational mode associated with the second unique trigger.

11. The system as claimed in claim 10 wherein recognizing the first unique trigger includes recognizing an update signal for updating a firmware of the memory sub-system.

12. The system as claimed in claim 10 wherein recognizing the second unique trigger includes recognizing a version signal for a reversion of a firmware of the memory sub-system.

13. The system as claimed in claim 10 wherein recognizing the second unique trigger includes recognizing a security signal for toggling a security mode of the memory sub-system.

14. The system as claimed in claim 10 wherein recognizing the second unique trigger includes recognizing a manufacturing signal for toggling a manufacturing mode of the memory sub-system.

15. The system as claimed in claim 10 wherein the memory sub-system includes a non-volatile memory array and a memory controller for managing the non-volatile memory array.

16. The system of claim 10, wherein receiving the patterned signal includes accepting the patterned signal in accordance with a determination that the patterned signal was received during an available period for accepting patterned signals.

17. The system of claim 10, wherein receiving the patterned signal comprises monitoring the patterned signal with a signal envelope follower and wherein recognizing the first unique trigger comprises monitoring the first unique trigger with a trigger envelope follower distinct from the signal envelope follower.

18. The system of claim 10, wherein the patterned signal further includes a speed negotiation signal, and wherein recognizing the first unique trigger comprises distinguishing the first unique trigger from the speed negotiation signal.
