FM1808B - 256Kb Bytewide 5V F-RAM Memory

General Description

The FM1808B is a 256-kilobit nonvolatile memory employing an advanced ferroelectric process.

A ferroelectric random access memory or F-RAM is nonvolatile but operates in other respects as a RAM.

Key Features

  • 256Kbit Ferroelectric Nonvolatile RAM.
  • Organized as 32,768 x 8 bits.
  • High Endurance 1 Trillion (1012) Read/Writes.
  • 38 year Data Retention (@ +75°C).
  • NoDelay™ Writes.
  • Advanced High-Reliability Ferroelectric Process Superior to BBSRAM Modules.
  • No Battery Concerns.
  • Monolithic Reliability.
  • True Surface Mount Solution, No Rework Steps.
  • Superior for Moisture, Shock, and Vibration.
  • Resistant to Negative Voltage Un.
