摘要:
A first apparatus, such as a die or a semiconductor package, has signal paths extending through the apparatus. The signal paths can include through vias and other components. The signal paths are operable to communicate with a second apparatus when the second apparatus is stacked with the first apparatus. The first apparatus also has pass gates. Each pass gate is configurable in response to a signal, to short a pair of the signal paths to enable substantially simultaneous testing of the signal paths. The pass gates may be configurable to isolate the signal paths during operation of the first apparatus.

External memory having a high density, high latency memory block; and a low density, low latency memory block. The two memory blocks may be separately accessed by one or more processing functional units. The access may be a direct memory access, or by way of a bus or fabric switch. Through-die vias may connect the external memory to a die comprising the one or more processing functional units.
摘要:
Electrostatic discharge susceptibility is reduced when assembling a stacked IC device by coupling a ground plane of a first semiconductor device and a ground plane of a second semiconductor device to place the ground plane at substantially a same electrical potential. Active circuitry on the first semiconductor device and active circuitry on the second semiconductor device are electrically coupled after the ground planes are coupled. Electrically coupling the ground planes of the first and the second semiconductor device creates a preferred electrostatic discharge path to ground, thus reducing potential damage to sensitive circuit elements.

A method for forming a magnetic tunnel junction (MTJ) for magnetic random access memory (MRAM) using two masks includes depositing over an interlevel dielectric layer containing an exposed first interconnect metallization, a first electrode, a fixed magnetization layer, a tunneling barrier layer, a free magnetization layer and a second electrode. An MTJ structure including the tunnel barrier layer, free layer and second electrode is defined above the first interconnect metallization by a first mask. A first passivation layer encapsulates the MTJ structure, leaving the second electrode exposed. A third electrode is deposited in contact with the second electrode. A second mask is used to pattern a larger structure including the third electrode, the first passivation layer, the fixed magnetization layer and the first electrode. A second dielectric passivation layer covers the etched plurality of layers, the first interlevel dielectric layer and the first interconnect metallization.
