A cure for amnesia

Article Abstract:

Dynamic random-access memories (DRAMS) store data using millions of cells, and need small amounts of electricity in order to function. The DRAM will instantly lose its data in the case of loss of power. Semiconductor producers are seeking alternatives to DRAMS. One potential alternative is the 'phase-state low electron-hole-number drive memory' or PLEDM. Cambridge University and Hitachi Cambride Laboratory have revealed the architecture of this new device, which can retain data when there is no power. Another development is the magnetic RAM, of which three versions have developed.
