Abstract: This disclosure concerns a system for dynamically controlling L2P table deallocation. The system receives a request to deallocate a set of entries of a logical-to-physical (L2P) table associated with a memory device, the set of entries corresponding to a memory device region comprising a plurality of logical translation units (LTUs) and, in response to receiving the request, deallocates a front set of LTUs of the region and a tail set of the LTUs of the region leaving a non-deallocated portion of the region. The system divides the non-deallocated portion of the region into a plurality of sub-regions and computes a size associated with a write command received from a host. The system dynamically selects a number of sub-regions in the plurality of sub-regions of the non-deallocated portion to deallocate based on the size associated with the write command.

Abstract: A new approach is proposed to support integration of EDR data from a plurality of EDR tools/sources into an Open XDR framework in an automated manner. First, EDR data generated by each of the plurality of EDR tools covering a plurality of assets is ingested into the Open XDR framework. The ingested EDR data is then normalized through a unified EDR data model. The normalized EDR data is further enriched with one or more new data fields to better correlate the EDR normalized data from the plurality of EDR tools. A plurality of alerts are then generated from the normalized and enriched data along one or more alert pathways to improve fidelity of the plurality of alerts. The plurality of alerts are correlated with the contextual information of the plurality of assets as well as information from other data sources to identify a set of incidents of suspicious activities.

Abstract: Methods, systems, and devices for enhancements for multiple data plane read commands are described. In some examples, a memory system may receive a set of multiple read commands and may determine whether a quantity of planes associated with the set of multiple read commands satisfies a threshold. Based on determining that the quantity of planes satisfies a threshold, the memory system may output a multi-plane read command. A memory device may obtain a multi-plane read command and may initiate a first transfer for a first plane based on obtaining the multi-plane read command. The memory device may then generate one or more single-plane commands for one or more planes associated with the multi-plane read command and may initiate a respective data transfer for each of the one or more planes.

The controller thereafter transmits the first aggregated device read memory command to the memory device.
