Innovative Silicon

DRAM memory IP

Innovative Silicon, Inc. (ISi) is a fast-growing, venture-backed company that develops and licenses Z-RAM - the world's densest, lowest-cost memory technology. Z-RAM  which stands for Zero-Capacitor DRAM is a direct replacement for today's DRAM technologies and is ideal for complex Systems-on-Chip (SoC), microprocessors, and stand-alone DRAMs. Innovative Silicon has harnessed the floating body effect of SOI semiconductor devices to develop memory cells that are twice as dense as existing DRAM and five times as dense as existing SRAM. Innovative Silicon proprietary memory technology, called Z-RAMTM (for Zero capacitor DRAM), uses a standard SOI logic processes without new materials or extra process or masking steps. For most SOC and Microprocessor ICs, this results in SOI being a lower-cost solution than bulk silicon.
