Abstract
A memory device includes a serial interface buffer that receives a hardware-decodable command and an extended interface command. The memory device also includes a logic module that directs the hardware-decodable command to a register for execution by a microcontroller. The logic module additionally loads a command received following the extended interface command into a sub-op-code register, wherein the logic module remains passive after loading the command received following the extended interface command into the sub-op-code register. Also included is a microcontroller that interprets the command in the sub-op-code register.
Claims20
An apparatus, comprising:
- a serial interface buffer configured to receive an extended interface command;
- a logic module coupled to the serial interface buffer and configured to load a code associated with the extended interface command into a sub-op-code register, wherein the logic module remains passive after loading the code into the sub-op-code register;
- and
- a microcontroller configured to interpret the code in the sub-op-code register to perform an operation.
A method, comprising:
- receiving an extended interface command of an extended interface command sequence during a first cycle;
- receiving a code of the extended interface command sequence during a second cycle;
- maintaining a hardware command decoder in a passive state responsive to receipt of the extended interface command and the code;
- and
- during a time in which the hardware command decoder is maintained in the passive state, performing one or more memory operations associated with the code using a microcontroller.
A method, comprising:
- receiving, with a serial interface buffer, an extended interface command;
- loading a code associated with the extended interface command into a code register;
- determining whether a fusible link is activated;
- and
- if the fusible link is active, interpreting the code in the code register to perform an operation.
