Unisantis Launches DFM as DRAM Alternative

Unisantis Electronics Singapore has released the company’s developments in Dynamic Flash Memory (DFM) technology, a leap forward in the industry’s search for alternatives to DRAM for future low-cost high-density embedded or standalone memory applications.

UnisantisDFM can offer faster speeds and higher density when compared to DRAM or other types of volatile memory.

Koji Sakui, Unisantis and co-inventor of DFM, commented “The memory industry has long-since accepted DRAM technology is nearing the end of its life, but its significant market means any replacement technologies must provide the right balance of performance, costs and future scalability. After significant internal research and testing, we are delighted to unveil DFM to the market as the leading long-term viable option to DRAM.”

DFM was presented this week for the first time at the 13th IEEE International Memory Workshop (IMW), by its inventors, Koji Sakui and Nozomu Harada from Unisantis.

DFM was well received by the IMW’s Scientific Committee, for having demonstrated not only performance benefits but also for its strategy of having been developed as an easy-to-implement DRAM replacement. Sakui’s paper entitled “Dynamic Flash Memory with Dual Gate Surrounding Gate Transistor (SGT)”, was presented publicly recently.

DRAM is a volatile, capacitor-based, destructive-read form of memory – and its challenge has long been to continue packing in more storage for lower cost, without increasing power consumption.

By utilizing TCAD simulation, Unisantis has proven DFM has a substantial potential to increase density 4X compared to DRAM. The scaling of DRAM has almost stopped at 16Gb, according to recent IEEE ISSCC (International Solid-State Circuits Conference) papers.

Modeling DFM at 4F2 cell density shows how perfectly structured DFM is. The design and development of DFM mean significant Gb/mm2 improvements, and today’s limits on DRAM (currently 16Gb) could immediately see increases to 64Gb memory using DFM’s radically enhanced cell structure.

Dynamic Flash Memory was developed by Unisantis with the proven technological principles of SGT Technology building on that work and the company’s innovations, particularly in memory semiconductors.

Following the recent unveiling, the company is now seeking to further its technical development, and in parallel, to testing and demonstrating the features and fuller potential of DFM externally with a series of memory and foundry partnerships.
