So...cache?

multibillion dollar company discovers the memory hierarchy

could the next big leap be integrating instructions and data in the same memory store?

The article does not say if they'd innovated enough to produce capacitor-based DRAM with the CPU on the same die. I guess it would come in 1GB variant if they managed that.

256 compute cores, each with its own memory

I haven't really kept up with it but doesn't the zen architecture have separate L1 and L2 for each core?

Even if it does it isn't the same thing. The article explains everything

NorthPole is made of 256 computing units, or cores, each of which contains its own memory... The cores are wired together in a network inspired by the white-matter connections between parts of the human cerebral cortex, Modha says. This and other design principles — most of which existed before but had never been combined in one chip — enable NorthPole to beat existing AI machines
