Memory Issues in Space & Medical Applications

How an alpha particle disrupts a memory bitThe Memory Guy was recently asked about using memories in a satellite. What would be a good technology to use in a space application?

The problem with space is that there is a lot of radiation.  Radiation on the earth’s surface is lower because it is stopped by the atmosphere, but in space there is an abundance of radiation that interferes with most semiconductors.  Radiation is also a concern in certain medical applications where a memory must maintain its contents while undergoing sterilization through irradiation.  Experiments on conventional flash memories have shown data loss at only 2% of the Continue reading “Memory Issues in Space & Medical Applications”

Fundamentals of Memory – Free Online Course

Fundamentals of Memory Course - EE TimesSome time ago The Memory Guy was asked by Numonyx (later acquired by Micron) to put together an online course for EE Times on memory technologies, explaining how each one works and where it is used.

Although the course was very well received, I never posted a link to it on The Memory Guy blog.  This post is intended to correct that error.

The course runs 75 minutes and covers the basics of DRAM, non-volatile RAM, SRAM, NAND flash, NOR flash, mask ROM, and EEPROM.  It explains each technology’s advances in size, cost and performance, leading up to the development of Continue reading “Fundamentals of Memory – Free Online Course”

Cheesecake and Floating Gates

Dr. Simon Sze, Co-Inventor of the Floating GateOne of the more fun aspects of last week’s Flash Memory Summit was the presentation of the Lifetime Achievement Award.  This is something that the show’s management has allowed me to do for the past four events.

This year’s award went to Dr. Simon Sze, who co-invented the floating gate transistor (the basis for all flash, EEPROM, and EPROM) at Bell Labs back in 1967.

Sze and his partner Dawon Kahng were finishing lunch in the company cafeteria with a cheesecake dessert.  The two discussed what would happen if a MOSFET was built with extra layers like the layers in the cake.  Their intent was to use semiconductors to replace Continue reading “Cheesecake and Floating Gates”
