Research brings analog computers just one step from digital

"processing-in-memory (PIM), an emerging computing paradigm that merges the memory and processing unit and does its computations using the physical properties of the machine — no 1s or 0s needed to do the processing digitally... a performance bottleneck at the interface of the processor and the memory... PIM computers aim to bypass this problem by merging the memory and the processing into one unit"
