Dates when DIMMs were released?

Here's a brief timeline of DIMM (Dual In-Line Memory Module) releases:

Early generations:

  1. SIMM (Single Inline Memory Module): Released in 1978 by Intel, SIMMs were the first type of memory module. However, they had limitations and were eventually replaced.
  2. SIMM was followed by:
    • JIMM (JEDEC-compliant Single Inline Memory Module): Introduced around 1984-1985, JIMMs improved upon SIMMs with a more robust design.
  3. The first DIMMs emerged in the late 1980s: These early DIMMs were essentially modified JIMMs with improvements for faster clock speeds.

DIMM generations by decade:

  1. 1990s (EDO and FPM):
    • EDO (Extended Data Out) DIMMs: Released around 1992-1993, EDO DIMMs offered improved memory access times.
    • FPM (Fast Page Mode) DIMMs: Introduced in 1994, FPM DIMMs provided faster performance than EDO DIMMs.
  2. 2000s (SDRAM and DDR):
    • SDRAM (Synchronous Dynamic RAM) DIMMs: Released around 1999-2000, SDRAM DIMMs offered higher speeds and lower power consumption.
    • DDR (Double Data Rate) DIMMs: Introduced in 2001, DDR DIMMs provided even faster performance and became widely adopted.
  3. 2010s (DDR3, DDR4, and newer standards):
    • DDR3 DIMMs: Released around 2007-2008, DDR3 DIMMs offered significant speed increases over DDR2.
    • DDR4 DIMMs: Introduced in 2014, DDR4 DIMMs provided faster speeds, lower power consumption, and improved memory density.
    • Newer standards (e.g., DDR5, LPDDR5): Released more recently, these newer standards continue to push the boundaries of speed, capacity, and energy efficiency.
