Sidense Announces 1T-OTP Macro Qualification

April 2, 2013

The NVMs have met all IP9000 assessment program requirements, making them fully qualified for read and field-programmable operations in high-temperature environments to support applications such as automotive electronics.

OTTAWA /Marketwire/ -- Sidense Corp., a leading developer of logic nonvolatile memory (LNVM) one-time programmable (OTP) memory IP cores, announced that its 1T-OTP macros for TSMC's 180 nm BCD 1.8/5 V/HV and G 1.8/5 V processes have met all of TSMC's IP9000 assessment program requirements. Sidense OTP macros are fully qualified for –40°C to 150°C read and field-programmable operations to support applications such as automotive electronics that require reliable operation and long-life data retention in high-temperature environments.

Sidense has already licensed its automotive grade 1T-OTP macros to many top fabless semiconductor companies, who have designed the macros into a wide range of leading-edge products. Customers including Fairchild Semiconductor, MAZ Brandenburg, Shanghai Haier IC, and ZMDI are using Sidense Automotive Grade OTP in a wide range of devices, including power-management ICs, sensors, and microcontrollers for applications in automotive, industrial, mobile, and consumer electronics.

"Our company is seeing an exciting and growing demand for 1T-OTP that supports power and HV processes," said Tom Schild, Sidense VP of Sales and Marketing. "We are helping many customers bring to market competitive new PMICs, sensors, and other products by offering cost-effective and highly reliable NVM qualified for demanding, high-reliability, high-temperature environments, in addition to being ideal for power and cost-sensitive mobile applications."

Sidense Automotive Grade 1T-OTP macros completed full qualification for high-temperature operating life at –40°C to 150°C and data retention storage life to 2000 hours at 150°C. This level of qualification was completed to support customers requiring devices to conform to AEC-Q100 Grade 0 specifications and provide data retention over the full operating temperature range, at full duty cycle, for more than 10 years.

Macros are available in a comprehensive range of off-the-shelf configurations, supporting small densities of 256 bits for configuration and trim applications up to 256 Kbps per macro for code storage and multiple NVM uses. Automotive-grade 1T-OTP provides many advantages, including small footprints to minimize cost, field-programmability, configurations with word widths up to 128 bits, and fast read access to allow executing code from OTP for many applications.

About Sidense
Sidense Corp. provides secure, very dense, and reliable nonvolatile, OTP memory IP for use in standard-logic CMOS processes, with no additional masks or process steps required. The company's innovative one-transistor 1T-Fuse architecture provides the "industry's smallest footprint, most reliable, and lowest power LNVM IP solution." With over 100 patents granted or pending, Sidense OTP provides a field-programmable alternative solution to Flash, mask ROM, and eFuse in many OTP and MTP applications.

Sidense SiPROM, SLP, and ULP memory products, embedded in more than 250 customer designs, are available from 180 nm down to 28 nm and are scalable to 20 nm and below. The IP is offered at and has been adopted by "all top-tier semiconductor foundries and selected IDMs." Customers are using Sidense OTP for analog trimming; code storage; encryption keys, such as HDCP, WHDI, RFID, and Chip ID; medical, automotive; and configurable processors and logic.
