Abstract
The invention is a random access memory assembly which is a key component of an object space manager which in turn is a key circuit in a garbage-collecting control unit for a computer system. An object space manager provides the means for deriving pointers to headers of objects from pointers to internal data of objects. The object space manager comprises an encoder that generates an object locator code for each memory cell in which an object is resident, a random access memory assembly for storing the object locator codes for all memory cells in which objects are resident, and an object locator which identifies the memory cell containing the header of an object by means of the object locator code for any memory cell occupied by the object.
