Patent ID: 7759715

Claim:
A memory cell comprising: a dynamic random access memory (DRAM) element that comprises two types of DRAM nanoparticles, the two types of DRAM nanoparticles being of different work function relative to one another; a nonvolatile memory (NVM) element that comprises two types of NVM nanoparticles, the two types of NVM nanoparticles having different trapping depths relative to one another; a tunnel dielectric; wherein the two types of DRAM nanoparticles are within a common plane at a first distance from the tunnel dielectric; and wherein: one of the two types of NVM nanoparticles is within a plane at a second distance from the tunnel dielectric that is greater than the first distance; and the other of the two types of NVM nanoparticles is within a plane at a third distance from the tunnel dielectric that is greater than the second distance.
