Increasing demand for higher-bandwidth DRAM drive TSV technology development. With the capacity of fine-pitch wide I/O [1], can be directly integrated on interposer or host chip and communicate with memory controller. However, there are many limitations, such as reliability testability, in developing technology. It is advantageous to adopt a logic-interface between stacked-DRAM thousands TSV.

Abstract Frame memory compression (FMC) saves power by reducing the data bandwidth for accessing reference frames of video coding standards in external memory. However, since continuously accumulated loss degrades performance standards, quality reconstructed frame must be improved.

In this study, a Huffman with fixed codebook designed to considerably reduce latency caused arithmetic...
