Abstract
A method and apparatus are provided for implementing input/output IO data management with an I/O buffer (IOB) directory in a compressed memory subsystem. Processor and I/O commands destined for a system memory are identified. I/O cacheline stores are accumulated in a free area of memory until a full block of data is received with only a directory to the data maintained on a memory controller chip. Then a pointer swap is provided to replace the existing compression block.
