This is a 1GB DDR (DDR1) laptop/notebook memory module from the brand WERX (or similar branding; the logo appears as “WERX” in comparable listings).
Key Specifications:
• Capacity: 1 GB
• Type: DDR SDRAM (first-generation DDR, not DDR2/DDR3/DDR4)
• Speed: PC3200 (equivalent to DDR-400)
• Clock Frequency: 400 MHz effective (200 MHz actual clock with double data rate)
• Form Factor: 200-pin SODIMM (Small Outline DIMM, designed for laptops/notebooks)
• Bandwidth: 3.2 GB/s (3200 MB/s theoretical peak)
• Voltage: 2.5V (standard for DDR1)
• CAS Latency: Typically CL3 (common for PC3200 modules)
• Configuration: Likely double-sided with 16 chips (8 per side), using 128Mx8 or similar chip organization; unbuffered, non-ECC
• Compatibility: For older laptops supporting DDR1 (roughly 2003–2007 era, e.g., some Dell Inspiron/Latitude, or systems with Intel Pentium 4/M or early Core Duo processors). Not compatible with DDR2 (also 200-pin but different notch) or newer standards.
