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

New NAND Player: Macronix

Macronix NAND FlashMacronix, a company known for its leadership in mask ROMs and low-density NOR flash has just entered the NAND flash market.  This adds a new player to a very small pool of competitors: Samsung, Toshiba, SanDisk, Hynix, Intel, and Micron.

The company’s first NAND products are SLC chips of two densities: 512Mb and 1Gb.  Compare this to the offerings of the market’s other participants which range up to 256Gb.  Spot price tracker InSpectrum doesn’t even track pricing of densities below 4Gb!

There still seems to be a good market for these low-density parts: According to WSTS  Continue reading
