EcoBit is an ultra-low-power embedded logic MTP solution that supports a SPEC on array density of up to about 4K bits, consumes only micro-Watts (uW) of power, 1K~100K-times electrical P/E-cycling endurance, and requires no additional masks or process changes. With excellent design of power domain and operating current management, EcoBit technology is the best embedded NVM choice for passive RFID tags, low-power mobiles, or IoT applications.
EcoBit silicon IP uses an innovative memory unit, differential sensing scheme, and superb power management to function predominantly at ultra-low voltage and achieve ultra-low-power operations. The memory array enables data-write functions in a byte or word (2-byte) unit to meet the needs of frequent write cycles on random addresses. EcoBit silicon IP’s efficient high-voltage system and power-managing driver/memory matrix reads and writes data using only passive power, yielding greater efficiency and flawless data writing and access.
Like all eMemory products, EcoBit is designed for common standard CMOS platforms: no additional masks or process changes are required, and the user interface is user-friendly and comprehensive. This silicon IP enables on-chip or in-system writing with micro-Watt (uW) low-power consumption, especially useful for passive or remote-sensing situations where the power supply is limited. In this way, customers can use EcoBit solution as an easy and economical way to achieve a short time-to-market.

EcoBit silicon IPs use ultra-low power to read and write data, thus accommodating applications with severe power restrictions. Cost and power consumption are key concerns for passive RFID tags, lower power sensors, battery-saving mobile ICs, and other IoT chips. EcoBit IP, the embedded logic MTP solution, is the best replacement for traditional EEPROM chips for such applications.
EcoBit is now available in 0.11 um logic technologies at two foundries. EcoBit memory blocks can be set to x1, x8, or x16 IO configurations.
