摘要： Systems and methods are provided for allocating memory to dissimilar memory devices. An exemplary embodiment includes a method for allocating memory to dissimilar memory devices. An interleave bandwidth ratio is determined, which comprises a ratio of bandwidths for two or more dissimilar memory devices. The dissimilar memory devices are interleaved according to the interleave bandwidth ratio to define two or more memory zones having different performance levels. Memory address requests are allocated to the memory zones based on a quality of service (QoS).

摘要： In a particular embodiment, a device includes memory address remapping circuitry and a remapping engine. The memory address remapping circuitry includes a comparison circuit to compare a received memory address to one or more remapped addresses. The memory address remapping circuitry also includes a selection circuit responsive to the comparison circuit to output a physical address. The physical address corresponds to a location in a random-access memory (RAM). The remapping engine is configured to update the one or more remapped addresses to include a particular address in response to detecting that a number of occurrences of errors at a particular location satisfies a threshold.

摘要： Various embodiments of methods and systems for hardware (“HW”) based dynamic memory management in a portable computing device (“PCD”) are disclosed. One exemplary method includes generating a lookup table (“LUT”) to track each memory page located across multiple portions of a volatile memory. The records in the LUT are updated to keep track of data locations. When the PCD enters a sleep state to conserve energy, the LUT may be queried to determine which specific memory pages in a first portion of volatile memory (e.g., an upper bank) contain data content and which pages in a second portion of volatile memory (e.g., a lower bank) are available for receipt of content. Based on the query, the location of the data in the memory pages of the upper bank is known and can be quickly migrated to memory pages in the lower bank which are identified for receipt of the data.

摘要： Systems and methods are provided for dynamically allocating a memory subsystem. An exemplary embodiment comprises a method for dynamically allocating a memory subsystem in a portable computing device. The method involves fully interleaving a first portion of a memory subsystem having memory components with asymmetric memory capacities. A second remaining portion of the memory subsystem is partial interleaved according to an interleave bandwidth ratio. The first portion of the memory subsystem is allocated to one or more high-performance memory clients. The second remaining portion is allocated to one or more relatively lower-performance memory clients.

摘要： Systems, methods, and computer programs are disclosed for kernel masking dynamic random access memory (DRAM) defects. One such method comprises: detecting and correcting a single-bit error associated with a physical address in a dynamic random access memory (DRAM); receiving error data associated with the physical address from the DRAM; storing the received error data in a failed address table located in a non-volatile memory; and retiring a kernel page corresponding to the physical address if a number of errors associated with the physical address exceeds an error count threshold.
