  • Patent number: 11461172
    Abstract: A storage device includes a nonvolatile memory device, and a controller that reads first data from the nonvolatile memory device. When a number of first errors of the first data is not smaller than a first threshold value, the controller determines whether the first errors include timing errors arising from a variation of signal transmission timings between the nonvolatile memory device and the controller and performs a retraining operation on the signal transmission timings when the first errors include the timing errors.

  • Patent number: 11422184
    Abstract: Systems, apparatuses, and methods for implementing a multi-die clock stop trigger are described. A computing system includes a plurality of semiconductor dies connected together and sharing a global clock stop trigger signal which is pulled high via a resistor tied to a supply voltage. Each semiconductor die has a clock generation unit which generates local clocks for the die. Each clock generation unit monitors for local clock stop triggers, and if one of the local triggers is detected, the clock generation unit stops local clocks on the die and pulls the global clock stop trigger signal low. When the other clock generation units on the other semiconductor dies detect the global clock stop trigger at the logic low level, these clock generation units also stop their local clocks. Captured data is then retrieved from the computing system for further analysis.

  • Patent number: 11403169
    Abstract: Systems, methods, and apparatus related to data recovery in memory devices. In one approach, a memory device encodes stored data. The memory device reads a codeword from a storage media and determines that a number errors in the codeword exceeds an error correction capability of the memory device. The errors are due, for example, to one or more stuck bits. In response to this determination, one or more data patterns are written to the storage media at the same address from which the codeword is read. The data patterns are read to identify bit locations of the stuck bits. The identified locations are used to correct bit errors of the read codeword that correspond to the identified locations. The corrected code word is sent to a host device (e.g., which requested data from the memory device using a read command).

  • Patent number: 11348659
    Abstract: Devices and techniques for an adjustable voltage drop detection threshold in a memory device are disclosed herein. A voltage drop detection threshold of a memory device is dynamically established. A power loss event is triggered when the supply voltage falls below the voltage drop detection threshold. An error parameter associated with performing multiple memory operations on the memory device is collected. The multiple memory operations are performed while applying a supply voltage at a second supply voltage level of the memory device which is less than a first supply voltage level established as a first operating voltage for the memory device. Determining whether the error parameter is below an allowable error threshold. In response to determining that the error parameter is below the allowable error threshold, the voltage drop detection threshold is established at a voltage level less than the first supply voltage level.
