Accelerating In-Page Logging with Non-Volatile Memory

A great deal of research has been done on solid-state storage media such as flash memory and non-volatile memory in the past few years. While NAND-type flash memory is now being considered a top alternative to magnetic disk drives, non-volatile memory (also known as storage class memory) has begun to appear in the market recently. Although some advocates of non-volatile memory predict that flash memory will give way to non-volatile memory soon, we believe that they will co-exist, complementing each other, for a while until the hurdles in its manufacturing process are lifted and non-volatile memory becomes commercially competitive in both capacity and price. In this paper, we present an improved design of In-Page Logging (IPL) by augmenting it with phase change RAM (PCRAM) in its log area. IPL is a buffer and storage management strategy that has been proposed for flash memory database systems. Due to the byte-addressability of PCRAM and its faster speed for small reads and writes, the ...
