Abstract: In certain aspects, a system includes a first clock source configured to generate a first clock signal, a second clock source configured to generate a second clock signal, a clock path, and an OR gate having a first input, a second input, and an output, wherein the output of the OR gate is coupled to the clock path. The system also includes a first clock gating circuit coupled between the first clock source and the first input of the OR gate, and a second clock gating circuit coupled between the second clock source and the second input of the OR gate.

Abstract: Aspects of the present disclosure control aging of a signal path in an idle mode to mitigate aging. In one example, an input of the signal path is alternately parked low and high over multiple idle periods to balance the aging of devices (e.g., transistors) in the signal path. In another example, a clock signal (e.g., a clock signal with a low frequency) is input to the signal path during idle periods to balance the aging of devices (e.g., transistors) in the signal path. In another example, the input of the signal path is parked high or low during each idle period based on an aging pattern.

Abstract: A memory interface circuit has a first differential receiver having a first input coupled to a first reference voltage source, a second differential receiver configured to receive a differential data strobe signal in a pair of complementary signals, a third differential receiver having a first input coupled to a second reference voltage source and a second input configured to receive one of the pair of complementary signals, a clock generation circuit configured to generate a read clock signal based on an output of the second differential receiver and using a qualifying signal output by the third differential receiver to qualify one or more edges in the read clock signal and a data capture circuit clocked by the read clock signal and configured to capture data from the output of the first differential receiver using the one or more edges in the read clock signal.

Abstract: In some aspects, an electronic device may receive a clock signal having a first frequency. The electronic device may receive, for a chip select training operation, a chip select signal having a pattern including high pulses and low pulses. The electronic device may perform, for a sampling window, the chip select training operation using the clock signal and the chip select signal, wherein the sampling window includes a quantity of pulses of the chip select signal. The electronic device may provide, via a first data in or out (DQ) pin, an indication of a first result of the chip select training operation for the high pulses of the chip select signal. The electronic device may provide, via a second DQ pin, an indication of a second result of the chip select training operation for the low pulses of the chip select signal. Numerous other aspects are described.

Abstract: In some aspects, an electronic device may detect a start of a voltage ramp transition period associated with changing a voltage at which an integrated circuit operates from a first voltage to a second voltage, wherein changing the voltage from the first voltage to the second voltage causes changes to one or more parameters that impact performance associated with the integrated circuit during the voltage ramp transition period. The electronic device may trigger, responsive to detecting the start of the voltage ramp transition period, a dynamic calibration mode that compensates for the changes to the one or more parameters that impact the performance associated with the integrated circuit during the voltage ramp transition period. The electronic device may exit the dynamic calibration mode responsive to detecting an end of the voltage ramp transition period. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to memory devices. In some aspects, a volatile memory device may receive, from a host device, a clock (CK) signal. The memory device may receive, from the host device, a command address (CA) signal associated with a continuous long burst pseudo-random binary sequence (PRBS) pattern. The memory device may perform a command bus training (CBT) based at least in part on the CA signal in relation to the CK signal. The memory device may provide, to the host device, pass or fail results associated with the CBT. Numerous other aspects are described.
