Detailed explanation-1: -Laptop DDR2 SO-DIMMs have 200 pins and often come identified by an additional S in their designation. DIMMs are identified by their peak transfer capacity (often called bandwidth).

Detailed explanation-2: -SDRAM DDR2 – the second generation of DDR memory operates at reduced voltage and power consumption. The lower voltage allows the maximum clock frequency to be increased to 800 MHz, leading to a transfer rate of up to 6400 MB/s (with a 64-bit interface).

Detailed explanation-3: -For DDR1 and DDR2 SO DIMM sockets, the pin count is 200 pins; for DDR3 SO DIMM sockets, the pin count is 204 pins; for DDR4 SO DIMM sockets, the pin count is 260 pins.
