Techniques For Sharing Memory Interface Circuits Between Integrated Circuit Dies

A circuit system includes a processing integrated circuit die comprising a first die-to-die interface circuit and a memory interface circuit. The circuit system also includes a second integrated circuit die comprising a second die-to-die interface circuit and a compute circuit that performs computations for the processing integrated circuit die. The first and the second die-to-die interface circuits are coupled together. The compute circuit is coupled to exchange information with the memory interface circuit through the first and the second die-to-die interface circuits.
