“JEDEC standard JESD235B for HBM leverages Wide I/O and TSV technologies to support densities up to 24 GB per device at speeds up to 307 GB/s. This bandwidth is delivered across a 1024-bit wide device interface that is divided into 8 independent channels on each DRAM stack. The standard can support 2-high, 4-high, 8-high, and 12-high TSV stacks of DRAM at full bandwidth to allow systems flexibility on capacity requirements from 1 GB – 24 GB per stack.

This update extends the per pin bandwidth to 2.4 Gbps, adds a new footprint option to accommodate the 16 Gb-layer and 12-high configurations for higher density components, and updates the MISR polynomial options for these new configurations. Additional clarifications are provided throughout the document to address test features and compatibility across generations of HBM components. ” (1)

I wanted to clarify that my recommendation of the TekWar TV series DVD set is based only on my confidence in the legendary William Shatner (of Rescue 911 fame), and not based on any actual experience with this show, or the related film (which isn't even on DVD…for some reason). Thank you.
