  • Patent number: 11972135
    Abstract: A memory system includes multiple dice having multiple planes. A processing device is coupled to the dice and performs controller operations including receiving a status indicator signal comprising a pulse that is asserted by one or more planes of the multiple dice. In response to receiving the pulse, the processing device performs at least one of: a first status check of dice operations being performed by the multiple dice at an expiration of a polling delay period; or a second status check of the dice operations in response to detecting the pulse being deasserted. The processing device terminates performances of status checks while the status indicator signal remains deasserted.

  • Patent number: 11962601
    Abstract: Systems and methods for automatically prioritizing computing resource configurations for remediation include receiving information describing configuration issues that may result in impaired system performance or unauthorized access, parsing that information and automatically analyzing configuration details of a user's private computing environment to determine that assets provide an environment in which configuration issues may be exploited to produce undesired results. Such systems and methods can generate assessments indicating the likelihood an issue can be exploited and potential impacts of the issue being exploited. Such systems and methods can use these assessments to generate a report prioritizing remediation of specific configuration issues for specific vulnerable assets based on the actual configuration of the user's computing resources and the data managed using those resources.

  • Publication number: 20230325323
    Abstract: Control logic in a memory device executes a first programming operation to program the set of memory cells to a set of programming levels. A first cache ready signal is generated, the first cache ready signal indicating to a host system to send first data associated with a second programming operation to an input/output (I/O) data cache of the memory device. A first encoded data value and a second encoded data value associated with each memory cell of the set of memory cells are generated. A second cache ready signal is generated, the second cache ready signal indicating to the host system to send second data associated with the next programming operation to the I/O data cache. The first data associated with the second programming operation is caused to be stored in a third data cache of the cache storage. A third cache ready signal is generated, the third cache ready signal indicating to the host system to send third data associated with the second programming operation to the I/O data cache.
