NeoEE
NeoEE is a single-poly embedded memory device offering the industry’s lowest implementation cost up to 500K program/erase cycles with low to medium densities (< 16K bits).
NeoEE carries out electronic program-/erase- operations for 16K bits (maximum) memory density and functions as a true rewritable memory technology, allowing up to 500K program/erase cycles with zero additional masking layers. A byte-write function is also incorporated in the NeoEE silicon IP to replace external EEPROM solutions and further reduce the package cost.

Technical Principles
NeoEE is composed of capacitive-coupling MOS devices and selectors. The memory-cell uses FN-tunneling from various MOS devices to store and expel electric charge from the floating gate, thereby turning the floating-gate transistor on or off during read cycles.
NeoEE has a main memory array that enables program, erase, and write functions on a block-unit as a page or a word, allowing it to meet the needs of intensive and frequent write cycles on random addresses. NeoEE further incorporates a high-voltage generator and power switches in order to simplify the user interface and power supply maintenance. The additional logic controllers enable switching of power sources for a range of operating modes.
Use Cases & Functionality
NeoEE can be applied in various product fields, such as user-preference settings in IC cards, code storage in MCUs and RFICs, configuration settings in NFC controllers, fuse devices in memory redundancy designs, and parameter trimming for analog/RF/HV/BCD circuits. The core function of NeoEE technology enables frequent changes of system setting parameters, making NeoEE an ideal replacement for traditional external SPI flash and EEPROM chips.
