With such a configuration, during the active mode, the memory device operates at the first voltage level as provided by the at least one register source, and during the self-refresh mode, the memory device operates at the second voltage level as provided by the at least one register source.

Abstract: A memory device and a memory controller can interface over a system data bus that has a narrower bandwidth than a data bus internal to the memory device. The memory device and memory controller transfer data over the system data bus on all transfer periods of a burst length, but send fewer bits than would be needed for the exchange to transfer all bits that can be read or written on the internal data bus of the memory device. The memory device can have different operating modes to allow for a common memory device to be used in different system configurations based on the ability to interface with the narrower bandwidth system data bus.

Abstract: Techniques and mechanisms to exchange communications via a printed circuit board (PCB) between a processor device and a memory device. In an embodiment, the processor device is configured based on a memory type of the memory device to an interface mode of multiple interface modes each corresponding to a different respective one of multiple memory standards. A voltage regulator (VR) is programmed, based on the memory type, to a VR mode to provide one or more voltages to the memory device via a hardware interface on the PCB. In another embodiment, x signal lines of an interconnect disposed in or on the PCB are each coupled between the processor device and the memory device to one another. The value x is an integer equal to a total number of signals of a superset of sets of signals each specified by a different respective one of the multiple memory standards.

Abstract: A cache controller with a pattern recognition mechanism can identify patterns in cache lines. Instead of transmitting the entire data of the cache line to a destination device, the cache controller can generate a meta signal to represent the identified bit pattern. The cache controller transmits the meta signal to the destination in place of at least part of the cache line.

Abstract: Dynamic monitoring of current draw by a memory device or memory subsystem can enable a power management system to adjust a memory access performance parameter based on monitored power usage. The system can generate a power usage characterization for the memory device and/or memory subsystem based on monitoring current draw for a known pattern, and then subsequently use the power usage characterization to determine how to adjust the memory access performance parameter.
