“Leveraging the ‘1 transistor 1 capacitor’ structure of our bit-cell, we build the smallest IP among all MTP vendors, while our competitors are at least 1.5 times bigger,” says Wen Chien Huang, CEO of Yield Microelectronics Corporation (YMC). These smaller IPs consumes lesser space in a device, enabling YMC clients to reduce the overall production cost.
By identifying the needs in the consumer electronics market, YMC allows its clients to use its multi-purpose IP mainly for use-cases that include trimming data with fuse-like IP, setting data with EEPROM and firmware storage with MTP.
This small-sized, cost-effective tech-stack offers high-end performance while allowing mass production. The agility of YMC’s novel IP is visible from its access time, which is the same level as embedded flash. On top of that, the solutions have the potential to withstand high temperature—up to 150 degree Celsius. “We have plans to establish our presence in the automotive space with its grade 0 technology which is ready to hit the market,” adds Huang. With its logic-based process, which requires much lesser than embedded flash, YMC helps its customers to shorten their lead time. Compared to embedded flash, the company’s IP enables its customers to saves 30 percent of cost while aligning well with their requirements. The number of additional masks that the firm’s IP requires is zero to two layers on top of the baseline of its 18 foundry partners. “We are the best choice to replace one time programmable (OTP) solutions. Compared to OTPs, our MTP enables 1,000 times of endurance, which increase the flexibility of design. In the middle-density market, MTP is also the best option for embedded flash replacement,” adds Huang.
In addition to extraordinary performance of the firm’s IP, YMC has foundry partners and a wide-spread customer base— 150 customers—across the globe with more than 800 projects merged with its IP. The firm has licensed its bit-cell to several big-name enterprises including TSMC, VIS, and Toshiba. Besides, there are 2 more foundries—HHGrace and Beijing Yandong Microelectronics in discussion. Into the next year, YMC continues to conduct discussions with other well-known foundries about porting its IP and the firm has on the anvil the desire to port its technology from mature process nodes, such as 0.18um, 0.15um, 0.13um to advanced ones like 90, 55, 45, 28nm process. Zealous to capture the electronics market, the company is rolling out plans to develop the next generation technology which is 30 percent smaller than its ancestor and verified by several foundries. Simultaneously, YMC is developing newer product lines such as OTP and fuse, both based on MTP technology. “We plan to build full range of embedded NVM product lines to help customers enhance competitiveness,” concludes Huang.
