The world’s smallest computer the size of a grain of salt

Already a lot of microelectronics manufacturers have boasted of their mini-computers

Which, as it turned out, are real giants compared to IBM’s crumb-sized computer with the grain size of 1 x 1 mm. The presentation took place at the IBM Think 2018 conference.

Despite its size, the computer has a power comparable to the processors of the 90s. Developers managed to place in it about a million transistors, RAM SRAM, a photodetector with a communication unit that transmits information using an LED photodiode and a photovoltaic power cell.

The unconditional advantage of a crumb-computer is the ability to work with a blocking machine, which will allow using it when tracking the chain of shipment of goods and detecting theft. According to experts, it will also find its application in smart homes and transport systems.

Within the next five years, cryptographic anchors — such as ink dots or tiny computers smaller than a grain of salt — will be embedded in everyday objects and devices,” said Arvind Krishna, IBM’s head of research.

IBM specialists continue to test a unique product, but it is too early to speak about its imminent appearance on the market. However, when it appears on the market, anyone can buy it, paying only 10 cents.
