ISi talks about Z-RAM memory technology

Building on advances in silicon-on-insulator (SOI) technology, Z-RAM exploits the so-called floating-body effect, where capacitance develops between the body of the transistor and the insulating layer. To that extent, Z-RAM exploits what would normally be regarded as an unwanted parasitic effect. The net result is the ability to store a binary one or zero, using no capacitor as such (Zero capacitor-RAM) and only one transistor, as opposed to the six transistors of an SRAM cell, or the one transistor and one capacitor of a DRAM cell.
