Abstract
A mechanism is provided within a 3D stacked memory organization to spread or stripe cache lines across multiple layers. In an example organization, a 128B cache line takes eight cycles on a 16B-wide bus. Each layer may provide 32B. The first layer uses the first two of the eight transfer cycles to send the first 32B. The next layer sends the next 32B using the next two cycles of the eight transfer cycles, and so forth. The mechanism provides a uniform memory access.
