Abstract
A preferred embodiment of the present invention includes a memory caching system that uses a method for allocating blocks of memory by: determining if the contents at a selected memory address are stored in the cache by comparing the selected memory address to the addresses stored in the directory, if the selected memory address is not in the cache, allocating a place in the directory for selected address, wherein, if a place in the directory for an address having the same cache line as the selected memory address is in the process of allocating or has been previously allocated, the selected memory address is allocated to that location of the pending or previous allocation.
