Apparatuses and methods for generating a unique identifier in a memory for I3C protocol

A memory device comprising:

• a current mirror coupled to an external resistor, wherein the current mirror is configured to provide a voltage having magnitude based on a resistance of the external resistor;
• an oscillator configured to generate a clock signal having a frequency based on the voltage provided from the current mirror;
• and
• a counter configured to receive the clock signal and a identifier generation operation enable signal, wherein in response to the identifier generation operation enable signal, counter is configured to provide a count value that adjust in response to the frequency of the clock signal, wherein the count value is used to assign a unique identifier for communication over a memory module management control bus.

A method comprising:

• during an identifier generation operation:
• providing, from a first memory device, a first count value to the M3C bus that changes at a frequency determined based on a first resistance value of a first external resistor;
• providing, from a second memory device, a second count value to the M3C bus that changes at a frequency determined based on a second resistance value of a second external resistor;
• in response to the first count value changing at a higher frequency than the second count value:
• assigning a first unique identifier to communicate over the M3C bus to the first memory device;
• and
• assigning a second unique identifier to communicate over the M3C bus to the second memory device;
• and
• in response to the first count value changing at a lower frequency than the second count value:
• assigning the second unique identifier to communicate over the M3C bus to the first memory device;
• and
• assigning the first unique identifier to communicate over the M3C bus to the second memory device.
