Phase change memory (PCM) is an emerging memory technology with many attractive
features: it is non-volatile, byte-addressable, 2–4X denser than DRAM, and orders of …

In some implementations, a programmable memory con troller is provided to control access
to different types of memory modules in a main memory. Non-volatile memory modules and …

Emerging solid-state storage media can significantly improve storage performance and
energy. However, the high cost-per-byte of solid-state media has hindered wide-spread …

Main memory is managed by receiving a command from an application to read data
associated with a virtual address that is mapped to the main memory. A memory controller …
