The MT4LSDT1664HG-13ED1 is a high-quality, synchronous SODIMM (Small Outline Dual In-line Memory Module) provided by Micron, one of the leading manufacturers in the memory module industry. This particular module is part of the SD/SDR SODIMM 144 pins category, designed for use in laptops and small-footprint computing devices needing high-speed data transfer and minimal latency. With specifications indicating a PC133 compliance, this module operates at a 133 MHz bus speed, which was considered top-tier speed at the time of its release. The '16Mx64' denotes its memory configuration, showing it is a 16 Megabits x 64 layout, essentially providing a total capacity of 128MB of RAM. This configuration was particularly popular during the late 90s and early 2000s for its balanced speed and capacity, suitable for the computing needs of that era. Furthermore, this model’s '-13ED1' suffix indicates specific versioning or timing characteristics defined by Micron, providing insights into its precise manufacturing specifications and performance benchmarks.
