A memory controller having a data receiver to sample data at a sample timing using a strobe signal, wherein the data and the strobe signal are sent by a memory device in connection with a read operation initiated by the memory controller, and a strobe receiver to receive the strobe signal, wherein a phase of the strobe signal has a drift relative to a reference by an amount. The memory controller further having a monitoring circuit to monitor the strobe signal and determine the amount of the drift, and an adjustment circuit to update the sample timing of the data receiver based on the amount of drift determined by the monitoring signal.

An operation timing condition associated with a memory device to be installed at a memory sub-system is determined. The memory device can include a cross-point array of non-volatile memory cells. The operation timing condition corresponds to a first operation delay timing margin setting for the cross-point array of non-volatile memory cells. A first set of memory access operations is performed at the cross-point array of non-volatile memory cells according to a second operation delay timing margin setting that is lower than the first operation delay timing margin setting. A first number of errors that occurred during performance of the first set of memory access operations is determined. In response to a determination that the first number of errors satisfies an error condition, a first quality rating is assigned for the memory device. In response to a determination that the first number of errors does not satisfy the error criterion, further testing is performed for the cross-point array of non-volatile memory cells based on one or more power level settings.

Methods, systems, and devices for techniques for detecting a state of a bus are described. A memory device may fail to receive or decode (e.g., successfully receive or successfully decode) an access command transmitted to the memory device via a bus. The bus may enter or remain in an idle state which may cause indeterminate signals to develop on the idle bus. A host device may obtain the indeterminate signals from the idle bus and determine that the indeterminate signals include an error based on a signal that develops on a control line of the idle bus. The signal may be associated with a control signal that indicates errors in a data signal when the control signal has a first voltage, and the control line may be configured to have the first voltage when the bus is idle.

The first organic substrate may include a plurality of first conductive lines arranged with a first pitch that may power one or more components of the memory device. The second organic substrate may be coupled with the memory device and the first organic substrate. The second organic substrate may include a plurality of second conductive lines arranged with a second pitch smaller than the first pitch and may be configured to route signals between the memory device with a host device.

A signal processing circuit includes a delay locked loop (DLL) circuit, a data output path circuit, and a first phase detector circuit. The DLL circuit is arranged to receive a memory clock signal, and generate a DLL output signal according to the memory clock signal and a DLL feedback signal. The data output path circuit is coupled to the DLL circuit, and is arranged to generate a DQS signal according to the DLL output signal. The first phase detector circuit is coupled to the data output path circuit, and is arranged to receive the memory clock signal and the DQS signal, and detect a phase difference between the memory clock signal and the DQS signal to generate a first phase detection result.

A system for testing memory includes logic that is configured to perform various normal memory operations (e.g., erase, read and write operations) on a memory device and to determine operational parameters associated with the memory operations. As an example, the amount of time to perform one or more memory operations may be measured, a number of errors resulting from the memory operations may be determined, or a number of memory cells storing noisy bits may be identified. One or more of the operational parameters may then be analyzed to determine whether they are in a range expected for counterfeit or defective memory. If so, the logic determines that the memory under test is counterfeit or defective and provides a notification about such determination.

A memory device includes at least one first register, a memory circuit, an analyzing circuit, and a control circuit. The memory circuit includes a plurality of bit cells. The analyzing circuit is configured to perform an analyzing process on the bit cells to generate an analyzing result. If the analyzing result indicates that a first bit cell of the bit cells fails, the control circuit establishes a repair process by controlling data to be written into the at least one first register and controlling the data to be read out from the at least one first register.

Automatic memory overclocking, including: increasing a memory frequency setting for a memory module until a memory stability test fails; determining an overclocked memory frequency setting including a highest memory frequency setting passing the memory stability test; and generating a profile including the overclocked memory frequency setting.

Glitch detection in microelectronic devices, and related methods, devices, and systems, are described herein. A device may detect and compare a number of pulses of a signal to a timing aperture to determine if any of the number of pulses is a glitch. The timing aperture, which may be based on a timing signal and/or one or more pulse width thresholds, may define an acceptable pulse versus a problematic glitch.
