A universal addressing system for use in a digital data processing system including a universal memory for storing data including instructions and at least one local system having access to the universal memory. The universal memory is organized into objects, and each item of data is associated with an object. Each object is specified by a unique identifier, and data is addressed by means of a logical address which specifies the UID of the object containing the data and the offset of the data in the object. A processor in the local system responds to instructions by providing memory operation specifiers to the universal memory. Each memory operation specifier specifies a memory operation and a logical address. The offset in the logical address may specify any bit in the object. The memory operation specifier also specifies a length in bits. The universal memory responds to the memory operation specifier by performing the operation specified by the memory operation specifier on the data item beginning at the location specified by the logical address and containing the specified number of bits.
