SilvoFlashᵀᴹ Technology Overview

SilvoFlashᵀᴹ refers "Single low voltages Flash, which utilizes the advantages of NOR Flash technology with floating-gate structure to enable Flash operation under a true single low voltage. SilvoFlashᵀᴹ is an ideal solution for code storage & parameter setting, designed in consideration with power, cost, memory density, and chip size to fit customers' requirements.

SilvoFlashᵀᴹ Technology's Advantages :

• Low Voltages (Vdd)

  - Single low voltages to read cell current

• Ultra Low Power Consumption

  - Low Power in Standby Mode

  - Low Power in Read Mode (Only needs Vdd in read, no charge pump circuit)

   - Low Power in PG/ER Mode (Maximal voltages at 7V in Macro IP)

• High Reliability and Date Retention

  Floating gate structure in Flash cell to store charge with high endurance and data retention.

-Endurance > 100K

-Data-retention > 10 years@85°C

• Logic Compatible and Scalable to 28nm

    - SilvoFlashᵀᴹ process is before logic devices, which is easily to make as embedded.

    - FG-FG spacing is screened by ground power. No cross coupling issue.

• Cost Effective

    - Small bitcell size and macro size

    - Less mask layers in embedded Flash

• Small System Footprint

SilvoFlashᵀᴹ technology makes MCU function with wide range Vdd at 0.9V~1.65V, 1.35V~1.65V, 1.6V~3.6V and etc.. Thus SilvoFlashᵀᴹ can help to take out some LDO & passive components(resistance, capacitance, diode...) to reduce power consumption and system footprint. Besides, the low Vdd feature of SilvoFlashᵀᴹ enables MCU operate at 0.9V~1.65V by a single button cell or AAA battery, which make system footprint smaller and then have more elgant/compact product design.
