Single-Port RAM ULL NEPTUNE 180 nm G

 

Ultra low leakage

Low Power

Patented

Embedding two key patents, the Single-Port RAM-uLL Architecture is THE optimal mix between ultra low Leakage, low Dynamic Power consumption and Voltage Scaling
It stars the proprietary architecture NEPTUNE-XAM:

  • The patented XAM bit-cell for minimizing dynamic power consumption
  • The "Thick and Thin" patent for leakage
  • The Self-sequenced circuitry for ensuring robustness against process deviations.

Key Benefits

  • Ultra low leakage even in generic process
    • Thick and Thin patent
    • Leakage is divided by a factor of 1 000
  • Data retention
    • Data retention while switching off the periphery when the memory is inactive
    • Wide range of power supply for data retention: from 0.8 V up to 3.3 V
  • Functionality from 2 V down to 1.4 V
    • More than 22% power savings compared to operating at nominal voltage
  • Low power consumption
    • Dolphin Integration XAM patented bit-cell
  • Optimal DfY

Available modes

Data Retention mode - included
For ultimate leakage savings: only the memory plane and the circuitry for retention would remain powered. Note that this data-retention mode requires 2 VDD power supply lines and one GND.

Byte mode - included
For more flexibility towards ultimate power savings, the capability of Byte-mode can be implemented to enable writing per single, double or quadruple Bytes RAM for more flexibility towards ultimate power savings.

BIST - optional
The most efficient testing solution for industrial fabrication test of instances

Error Correcting Code
Enables detecting two errors and correct one error per word.

DC-DC Converter
With mode control can embed the generation of the appropriate VDD33 from 1.8 V (+/- 10%).
