Floadia Announces MTP IP without extra Mask Available on 55nm

Tokyo, Japan -- Oct 31st, 2022 – Floadia Corporation (Floadia), a leading provider of embedded non-volatile memory intellectual property (IP) announces that its high-quality Multi-Time Programmable memory IP (MTP) is now available on the 55nm process platform with the product name “ZT”, which is capable of 10 years data retention at 85 degrees Celsius.

Traditionally, MTP IP without extra masks is fully compatible with standard logic processes. In general, such MTP can only be enabled at process node with the oxide thickness thicker than 100 Angstroms. However, such traditional MTP developments face challenges in sustaining good reliability due to oxide thickness scaling along with process migration. As process nodes move beyond 55nm, it becomes very difficult to develop reliable MTP due to thin oxides that cannot sustain good data retention. Despite such difficulties, MTP of small density will be all-time requirements. Applications in sub-55nm process geometries that require very small MTP densities for code storage are forced to switch to eflash IP, typically requiring more than 10 additional masks, driving up the overall chip cost. By adopting special cell layout and design technics, Floadia's ZT can achieve 10 years data retention at 85 degrees Celsius after 10,000 program/erase cycles without adding any additional mask and is now available on 55nm platform at one major foundry headquartered in China.

Floadia ZT has already been adopted by Japanese IDM and foundries for a variety of automotive applications including drive line system, pressure sensor, motor driver and engine control system chip. The newly unveiled ZT IP on the 55nm process platform is a 1kbit macro, and is a good fit for consumer applications to replace external discrete EEPROM components. By adopting ZT IP instead of having discrete EEPROM component, it can increase the chip integration level, reduce the BOM cost and PCB size, and create compact form factor. In the meantime, ZT uses the FN tunneling methodology to achieve low power consumption during the program and erase operations. ZT has also been adopted by a Chinese chip maker for its smart lighting product planned to be market-ready in 2023.
