Development of a Breakthrough Technology for Achieving Low Voltage Operation in System LSI by TOSHIBA
System LSI constitute the core components of digital products, where their operation voltage has a major impact on an overall power consumption of a product. However, up to now, voltage scaling of cutting edge system LSI has presented a big technological challenge due to loss of stability in memory function of its embedded SRAM which occurs at low voltage. The smaller size of the memory cell transistor of SRAM makes SRAM susceptible to transistor variability at low voltage in comparison to other logic circuits. In order to overcome this issue, Toshiba has developed a SRAM circuit technique which results in a low voltage operation in system LSI, paving the way in reduced power consumption in digital products.

Development of scalable High-Speed MRAM technology for system LSI Embedding by NEC
Due to the progress in reducing cell size and the large capacity of system LSI, power consumption has increased. The current demands require reduced power consumption, which is partially accomplished by switching off during stand-by mode, a function that requires easy-use nonvolatile memory. In response to these market demands, NEC developed the world’s fastest SRAM-compatible MRAM with operation speed of 250 MHz in November 2007, and 32 Mbit MRAM for embedding in SoCs in February 2009.

Development of 32Mb MRAM for SoCs by NEC
An increase in functionality of system LSIs has a direct effect in an increase in their power consumption. But there is an increasing demand in lowering the power consumption of electric appliances that use system LSI. The most effective way to decrease the power consumption in system LSIs is for them to enter into a standby state where their power will be cut off resulting in increasing demand in use of embedded non-volatile memory macros in system LSIs.

NEC’s 12 Mega pixel system LSI for mobile phone
It was just matter of time to see a mobile phone with a high picture quality comparable with that of digital still cameras. NEC’s new developed system LSI achieved just that. The “CE143″ which NEC is planning its sample shipping on March of this year has a basic image processing function and with incorporation of CMOS image sensor it can provide a camera capability to the mobile phones.
