Processing-In-Memory, 1960s-Style

Famous photo of Apollo 11's Buzz Aldrin on the moon.There’s a surge of interest these days in Processing in Memory or PIM.  Some call it “Compute in Memory.”  Either way, it often involves adding small amounts of logic to a memory chip to allow it to offload tasks from the CPU.

There are various reasons to do this.  The most important is that PIM frees the CPU to do other chores.  PIM also can reduce Continue reading “Processing-In-Memory, 1960s-Style”

ReRAMs find a Neuromorphic Role in Owl-Inspired Object Location

Photo of Ron Neale, Renowned Phase-Change Memory ExpertIn his latest post on The Memory Guy, contributor Ron Neale reviews a novel use for ReRAM cells in which a neural processing system mimics the direction-finding mechanism of a barn owl’s ears.  This is based on research performed by CEA-Leti in France, which was recently published in the journal Nature.


The potential for the use of the unique characteristics of ReRAMs, PCM and CeRAMs as brain-gates, neuromorphic devices, and in-memory computation has long been recognised.

In a paper recently published in Nature , inspired by the auditory system of the barn owl, a team from: CEA-Leti, Continue reading “ReRAMs find a Neuromorphic Role in Owl-Inspired Object Location”

The Rarely Seen, But Beautiful Content-Addressable Memory (CAM)

Photo of a D3103 chip from a 1973 Intel advertisementAlthough The Memory Guy spends more time writing about NAND and DRAM than almost anything else, several other memory types ship in high volume that many people have never heard of.  One of these is the Content-Addressable Memory, or CAM.

CAMs are kind of backwards.  In a normal memory chip you input Continue reading “The Rarely Seen, But Beautiful Content-Addressable Memory (CAM)”
