  • Patent number: 12658231
    Abstract: In an apparatus, a memory controller, a memory device, and a method for switching frequencies of clock signals to reduce power consumption, when the memory device performs an internal operation according to a command of the memory controller, a frequency of a clock signal of the memory controller is changed. The memory controller switches the frequency of the clock signal to a low frequency according to assertion of a status signal that indicates a busy operation status of the memory device according to the command, and switches the frequency of the clock signal to a high frequency according to de-assertion of the status signal that indicates a ready operation status of the memory device.

  • Patent number: 12658256
    Abstract: A memory device includes several computing memory cells each storing a weight value and comprising a first and a second switch elements and a first and a second resistors. The first switch element receives a sensing current and a first input signal related to the input value. The first resistor selectively receives the sensing current through the first switch element in response to the first input signal. The second switch element receives the sensing current and a second input signal related to the input value. The second resistor selectively receives the sensing current through the second switch element in response to the second input signal. When the sensing current flows through the first resistor or the second resistor, the computing memory cell generates a first voltage difference or a second voltage difference corresponding to an output value equal to product of an input value and a weight value.

  • Patent number: 12640212
    Abstract: The present disclosure configures a system component, such as memory sub-system controller, to perform empty page scan operations. The controller, in response to a request to perform an empty page scan operation, identifies a portion of a set of memory components that is empty and ready to be programmed. The controller generates an order in which to perform the empty page scan operation for a plurality of regions of the identified portion of the set of memory components. The controller determines whether a first region of the plurality of regions in the order fails the empty page scan operation before a second region of the plurality of regions is scanned. The controller terminates the empty page scan operation early to prevent performing the empty page scan operation for one or more remaining regions of the plurality of regions of the identified portion.
