Adaptive frequency control for high-speed memory devices

A method comprising:

• operating both a memory controller and a memory die simultaneously at an initial operating frequency during a read operation, wherein the memory controller is in a memory sub-system that controls the memory die after the memory die is assembled into a memory device;
• detecting an occurrence of an error event during the read operation;
• setting an error threshold criterion;
• determining, with respect to the initial operating frequency, an adjusted value for a current operating frequency of at least one of the memory controller and the memory die;
• determining whether the adjusted value of the current operating frequency satisfies the error threshold criterion;
• and
• responsive the determining that the adjusted value of the current operating frequency satisfies the error threshold criterion, updating the operating frequency of the at least one of the memory controller or the memory die to the adjusted value of the current operating frequency.

A system comprising:

• a plurality of memory dies;
• and
• a processing device in a memory controller, operatively coupled to the plurality of memory dies, to perform operations for each of the plurality of memory dies, the operations comprising:
• operating both a memory controller and a memory die simultaneously at an initial operating frequency during a read operation;
• detecting an occurrence of an error event during the read operation;
• setting an error threshold criterion;
• determining, with respect to the initial operating frequency, an adjusted value for a current operating frequency of at least one of the memory controller and the memory die;
• determining whether the adjusted value of the current operating frequency satisfies the error threshold criterion;
• responsive the determining that the adjusted value of the current operating frequency satisfies the error threshold criterion, updating the operating frequency of the at least one of the memory controller or the memory die to the adjusted value of the current operating frequency;
• and
• responsive the determining that the adjusted value of the current operating frequency does not satisfy the error threshold criterion, continuing to operate the memory controller and a memory die at the initial frequency.
