The AS4C16M16MD1-6BCN is a DRAM module developed by Alliance Memory, characterized under the SDRAM PC166 category. Despite its classification, its specifications suggest advanced capabilities more in line with DDR4 technology, featuring 4Gbit DDR4 memory organized as 256M x 16 at a speed of 1200MHz within a commercial temperature range. This discrepancy might imply that the part bridges technological generations, offering high-density memory and fast data rates beneficial for applications in modern computing and high-performance devices. The '6BCN’ suffix typically represents the package type and temperature range, with this part being designed for commercial applications where operational integrity between 0°C and 70°C is paramount. Its high-density memory support and speed are ideally suited for applications requiring large amounts of fast, accessible storage, such as servers, workstations, and high-end personal computers.
