DOUBLE POLY-SINGLE METAL CELL

( Double Poly-Two metal cell will be smaller by 10 to 15%)

  • THE CELL- TECHNICAL ADVANTAGES

  • Reduced Field on Floating gate due to two sided select gate spacing the diffusion away from FG edge
  • Integrated Select/Control gate allow cells to be in depletion- No Over Program or Over Erase issues and no Vt distribution issues
  • Use of total FG area for Program/Erase reduce stress on tunnel oxide
  • Array configurable as EEPROM or Flash
  • Disturbs have been designed out

  • CELL_COST ADVANTAGES

  • Standard Processing with minimum additional masks -4 to 5 for cell in 0.25 microns
  • Processing of NVM prior to the CMOS and Analogprocess steps ensure minimum impact on standard device
    characteristics
  • Standard Processing for low cost manufacture

Read about the cell and Technology

THE ADVANTAGES MAKE THE CELL APPLICABLE IN:

o... Automotive - High reliability, high temperature range (-40 to 125C or -55 to 150C) operation

o... Medical - Very High reliability application

o... Industrial - High reliability, high temperature and low cost application

o... Consumer - low cost large volume application

CELL SIZE SCALING


SCALING WITH TECHNOLOGY:

o... Problem for most enbedded Non-Volatile memories due to-
. .a)need for minimum number of additional steps
. .b)high voltages required
. .c)punch trough problems

o... SimpleEE on the other hand scales well with technology with minimum change in process, lower high voltage needs and no punch through effects.
