Diplomacy, reform, and a convenient stone
Mongkut came across a remarkable object: a four-sided, black stone monolith, about a meter high and inscribed with an unusual script. The stone would become known as the Ramkhamhaeng Stele.
The discovery of the Stele was, as it turned out, serendipitous. Over five centuries, European powers colonized virtually every other territory on Earth

The most expensive part of HBM is not the DRAM. It is the piece of silicon underneath it. HBM moves data over a very wide parallel bus, roughly 1024 bits per stack. Every one of those wires has to be routed through a silicon interposer sitting between the memory and the compute…
