August 13, 2012 -- Novocell Semiconductor, Inc. announced today that its Smartbit-based antifuse OTP memory designs have completed the rigorous exposure to long-term high-temperature exposure required for military and automotive applications, as well as survived extended exposure to radioactive Cobalt-60 necessary to establishing rad-hard (radiation hardened) status.
Within the past year, Novocell Semiconductor has extended the routine high-temperature operating life (HTOL) temperature range to provide long-term chip exposure at up to +150°C, and routinely performs the early life failure-rate (ELFR) testing up to this same temperature, versus the lower industry standard of +125°C. ELFR qualification testing is performed to meet or exceed conditions specified within automotive specification AEC-Q100-005, and HTOL qualification testing is performed to meet or exceed conditions specified by industry standard JESD22-A108, automotive specification AEC-Q100-005, and military specification MIL-STD-883H-1005.
In a number of cases, Novocell has been providing product-qualification testing to confidential customers for critical applications at up to +175°C, to meet special application requirements. For high-atmosphere, orbital, and space applications, as well as for nuclear military applications, Novocell NVM IP has been tested to demonstrate radiation tolerance to 100kRad (Si) in accordance with MIL-STD 883 Test Method 1019.
"Novocell’s OTP IP has performed admirably in our aerospace-targeted transceiver products," said Chuck Tabbert, Vice President of Ultra Communications, the 2005 spin-out from Peregrine Semiconductor. "We were not only impressed with the unique technology behind the IP, but have been very pleased with the high degree of reliability we see exhibited by the embedded NVM in actual products, even in some extraordinarily harsh environments."
All Novocell products continue to be based on the exclusive Smartbit bit-cell design and dynamic-programming technology, and provide the highest level of programming and data-storage reliability and security available in the anti-fuse OTP segment, particularly at low-power, advanced-process nodes. All five of Novocell's full line of embedded non-volatile memory products, Novobits, Novobits SPX, NovoBytes, NovoBytes MTP, and NovoHD, are available to meet the rigors of the most-demanding automotive, aerospace, and military applications.
- Novobits is a register-type architecture OTP, designed as a dense and highly reliable efuse replacement and available in sizes ranging from 8bits to 256bits. Novobits SPX, a special version of Novobits, is available specifically for analog trimming and calibration and includes convenience features such as serial-mode I/O and a special preview mode for data testing in analog mixed-signal applications.
- NovoBytes is a ROM-style block-array OTP offering access times under 8ns and ability to program from standard IO voltage with < 2.5mA current, particularly well-suited to feature enablement and part configuration. NovoBytes is available from 8bits to 32kbits in a choice of word sizes.
- NovoBytes MTP is a special multi-time-write version of NovoBytes. NovoBytes MTP was the first hybrid OTP/ MTP solution to provide virtual multi-time-write functionality in 2010, and is available off-the-shelf in 2x-, 4x- and 8x-write versions, or may be customized in configurations to up to 1000x writes. NovoBytes MTP is available in densities from 8bits to 32kbits, and is suited to better manage part reconfiguration and inventory optimization challenges in that fast-changing mobile market.
- NovoHD is an ultra-high-density ROM-style OTP available in sizes up to 4Mbits for high-capacity code storage, security, and feature enablement in low-power, advanced-node applications.
All Novocell NVM products are built on the and programming process, rely on only standard CMOS processes with no additional masks or post-process steps, and feature a unique High-Voltage Generator that eliminates the need for a area-consuming external charge pump, requiring only the standard process I/O voltage to achieve oxide breakdown. The IP-macros program each bit dynamically, while monitoring the programming process to completion which then triggers a logic done confirmation signal. No additional error-correction circuitry, additional chip area for redundant bit inclusion, or other chip footprint waste is required.
Smartbit-based OTP NVM IP is qualified at all major foundries, and the exclusive dynamic-programming methodology makes Novocell OTP the most process independent and foundry independent anti-fuse NVM available, with the technology available and scalable all the way from the larger legacy .350µm process node to advanced nodes including 20nm and beyond.
