Toshiba has announced the development of a flash memory
embedded process based on 65nm logic process and a single-poly
non-volatile memory (NVM) process based on 130nm logic and analog power
process. The new process technologies were developed for low-cost
applications such as microcontrollers (MCU), wireless communication ICs,
motor controller drivers and power supply ICs.
The IoT
market is seeing strong demand for low power consumption in areas
including wearable and healthcare-related equipment. In response,
Toshiba has adopted SST's third-generation SuperFlash cell technology,
in combination with its own 65nm logic process technology. Toshiba has
also fine-tuned circuits and manufacturing processes in developing its
ultra-low power consumption flash embedded logic process.
Microcontrollers for consumer and industrial applications that apply the
process can lower power consumption to approximately 60% that of
current mainstream technology, according to the company.
Following
the first series of MCUs, Toshiba plans to release sample BLE
(Bluetooth Low Energy) products, the short-range wireless technology, in
fiscal year 2016. The company also plans to apply the 65nm process to
its wireless communication IC product family that can optimize use of
low power consumption characteristics, including NFC controllers and
contactless cards.
In applications where significant
cost reductions are a concern, Toshiba has developed an NVM embedded
process that adopts Taiwan-based Yield Microelectronics' (YMC)
single-poly MTP (Multi-time programmable) cells on Toshiba's 130nm logic
process technology. Applying MTP specifications for write times
improves the process' performance while limiting increased steps in mask
pattern lithography to three or fewer, and even none.
In
addition, by using MTP to adjust output accuracy, Toshiba will expand
its product line-up in fields where higher accuracy is essential, such
as power management ICs, the company said.
Sample
shipments of the 130nm-NVM and 65nm-flash are scheduled for the fourth
quarter of 2015 and the second quarter of 2016, respectively.
