Embedded Memory Shrinks to 40nm

摘要

At the recent Linley Tech Mobile Conference in San Jose, Kilopass announced the first nonvolatile embedded memory that is reprogrammable up to 1,024 times and is fully compatible with digital-IC processes in 40nm bulk CMOS. The company has also produced test chips in 28nm CMOS. Branded Itera, the new memory is licensed as intellectual property (IP) to chip designers. It's available now for 40nm processes at GlobalFoundries, TSMC, and UMC. Itera will be available for 55nm and 65nm processes in 3Q11 and for 28nm processes in 4Q11. Block sizes range from 32 bits to 1Mb, and write endurance ranges from 104 to 1,024 cycles. For the first time, Kilopass is replacing its proprietary I/O interface with an industry-standard interface (Open Core Protocol 3.0), which is no faster but will ease design integration.
