Semiconductor Memories

A brief overview on memory architecture and processes for several conventional types within the MOS family. Current trends and limitations would be discussed before leading to some insight on the next generation of memory products.

A Built-In Self-Repair Scheme for Semiconductor Memories with 2-D Redundancy

Embedded memories are among the most widely used cores in current system-on-chip (SOC) implementations. Memory cores usually occupy a significant portion of the chip area, and dominate the manufacturing yield of the chip. Efficient yield-enhancement techniques for embedded memories thus are important for SOC. In this paper we present a built-in self-repair (BISR) scheme for semiconductor memori...

Electrochromic conductive polymer fuses for hybrid organicÕinorganic semiconductor memories

We demonstrate a nonvolatile, write-once-read-many-times ~WORM! memory device employing a hybrid organic/inorganic semiconductor architecture consisting of thin film p-i-n silicon diode on a stainless steel substrate integrated in series with a conductive polymer fuse. The nonlinearity of the silicon diodes enables a passive matrix memory architecture, while the conductive polyethylenedioxythio...

Modeling of retention characteristics for metal and semiconductor nanocrystal memories

The charge retention characteristics of metal nanocrystal (MNC) and semiconductor nanocrystal (SNC) memory devices are comparatively studied in this paper. A charge retention model is proposed, taking into account the quantum confinement effect, to account for the better retention characteristics of metal nanocrystal memory observed in the experiment. Simulation results are in good agreement wi...
