Abstract: A memory device that performs internal ECC (error checking and correction) can selectively return read data with application of the internal ECC or without application of the internal ECC, in response to different read commands from the memory controller. The memory device can normally apply ECC and return corrected data in response to a normal read command. In response to a retry command, the memory device can return the read data without application of the internal ECC.

Abstract: Technologies for fast boot-up of a compute device with error-correcting code (ECC) memory are disclosed. A basic input/output system (BIOS) of a compute device may assign memory addresses of the ECC memory to different processors on the compute device. The processors may then initialize the ECC memory in parallel by writing to the ECC memory. The processors may write to the ECC memory with direct-store operations that are immediately written to the ECC memory instead of being cached. The BIOS may continue to operation on one processor while the rest of the processors initialize the ECC memory.

Abstract: An Artificial Intelligence (AI)-based data processing system processes current data to determine if the quality of the current data is adequate to be provided to data consumers and if the quality is adequate, the current data is further analyzed to determine if an impacted load including changes to dimension data of the current data or an incremental load including changes to fact data of the current data is to be provided to the data consumers.

Abstract: A memory subsystem includes memory devices with space dynamically allocated for improvement of reliability, availability, and serviceability (RAS) in the system. Error checking and correction (ECC) logic detects an error in all or a portion of a memory device. In response to error detection, the system can dynamically perform one or more of: allocate active memory device space for sparing to spare a failed memory segment; write a poison pattern into a failed cacheline to mark it as failed; perform permanent fault detection (PFD) and adjust application of ECC based on PFD detection; or, spare only a portion of a device and leave another portion active, including adjusting ECC based on the spared portion. The error detection can be based on bits of an ECC device, and error correction based on those bits and additional bits stored on the data devices.

Abstract: A system can predict memory device failure through identification of correctable error patterns based on the memory architecture. The failure prediction can thus account for the circuit-level of the memory rather than the mere number or frequency of correctable errors. A failure prediction engine correlates hardware configuration of the memory device with correctable errors (CEs) detected in data of the memory device to predict an uncorrectable error (UE) based on the correlation.

Abstract: A memory module has a registering clock driver (RCD) that issues two column address strobe (CAS) commands with a single memory access command to exchange a double amount of data per dynamic random access memory (DRAM) device per memory access command. With double the amount of data per DRAM device, the memory module can provide double the pseudo channels as compared to a memory module where a single CAS command is issued per access command. The RCD can time division multiplex separate first commands for a first group of the DRAM devices from second commands for a second group of the DRAM devices on the command/address (CA) bus.
