Implementation of a high speed multiport register file in a 1.8V, 0.25 μm CMOS bulk and SOI technology

The experimental hardware results of a high speed 8-ports, 32 Words × 64-bit register file in 1.8 V, 0.25 μm CMOS bulk and SOI silicon technology are presented. Such a register file is designed for bulk technology but is also remapped and fabricated in SOI technology without any body contacts. It is shown that the register file in SOI achieves more than 20% performance gain over the counterpart.
