Abstract
The preferred embodiments described herein provide a three-dimensional memory cache system. In one preferred embodiment, a modular memory device removably connectable to a host device is provided. The modular memory device comprises a substrate, a cache memory array, a three-dimensional primary memory array, and a modular housing. The cache memory array and the three-dimensional primary memory array can be on the same or separate substrates in the modular housing. In another preferred embodiment, an integrated circuit is provided comprising a substrate, a cache memory array in the substrate, and a three-dimensional primary memory array above the substrate. Other preferred embodiments are provided, and each of the preferred embodiments can be used alone or in combination with one another.
