Summary :

We propose a novel capacitorless twin-transistor random access memory (TTRAM). The 2 Mb test device has been fabricated on 130 nm SOI-CMOS process. We demonstrate the TTRAM cell has two data-storage states and confirm the data retention time of 100 ms at 80. TTRAM process is compatible with the conventional SOI-CMOS and never requires any additional processes. A 6.1 ns row-access time is achieved and 250 MHz operation can be realized by using 2 bank 8 b-burst mode.
