FJG RAM

FJG RAM, short for Floating Junction Gate Random Access Memory, is a type of computer memory invented by Oriental Semiconductor Electronics, Ltd.[1]

The FJG RAM has an ultra-compact cell area of 4F² (F refers to feature size) and a capacitorless cell configuration. It is made without exotic process steps, materials or new process tools, and the process for making the device is available from all existing DRAM fabs. Due to the absence of a capacitor, the FJG cell process is more compatible with logic processes, allowing its use not only in standalone DRAM applications but also in embedded-DRAM applications. Other properties include non-destructive-read and the possibility for DRAM designers to use shared sense-amplifiers to reduce the complexity of peripheral circuits.[2]

As of April 2016, there was little evidence of ongoing development or near-term commercialization efforts.
