16 bit without ECC and 18 bit with ECC

RIMMs operate at speeds of 600 MHZ (PC600) or 800 MHz (PC800). All installed RIMMs must operate at the same speed, and have the same ECC or non-ECC rating. The operating speed is different than the data path size. RIMMs are avilable in 16- or 32-bit data path.
A path made for an electric current is classified as a conductor and can come in the form of many shapes and sizes.
The data path size for a 64-bit processor is 64 bits. This means it supports memory addresses, integer sizes and data paths that are 8 octets wide.
800 MHz and have a 64 bit wide data path and at least a 36 bit wide address path
Current goes path of least resistance. But if u have two resistances in paralell only the majority will go through the smaller resistance some Porportional Amount will "flow" through the larger resistor. Depends on resistance sizes and voltage slap plied as to how much current
SIMMs have a 32-bit data path.
The width of a data bus is referred to as the data path size. An example would be a 16 bit bus can transmit 16 bits of information
Absolute path: Path from root directory (it is the same place, wherever the current path is) Relative path: Relative to the current path.
The data path size of a current DIMM (Dual In-line Memory Module) typically varies based on the type and generation of the memory. For DDR (Double Data Rate) SDRAM, the data path size is commonly 64 bits for standard DIMMs used in most desktop and laptop computers. This means each DIMM can transfer 64 bits of data simultaneously, effectively doubling the data transfer rate with each clock cycle. At Uncodemy, which offers the best data science course in Thane, Mumbai, Navi Mumbai, Delhi, Noida, and other locations across India, students learn about the importance of memory architecture in computer systems, including the role of DIMMs in enhancing performance. Additionally, specialized DIMMs, like DDR4 or DDR5, may support wider data paths in certain configurations, contributing to improved bandwidth for high-performance computing applications.

There are 3 kinds of RAM: SIMM (Single inline memory module), RIMM (Rambus inline memory module) & DIMM (Dual inline memory module).SIMMs have a 32-bit data path and are rated by speed, measured in nanoseconds, Common SIMM speeds are 60, 70, or 80 ns, the smaller the speed rating is, the faster the chip.DIMMs have a 64-bit data path, and are rated by the amount of memory they hold which can be anywhere from 8MB to 2GB. The 240-pin DDR2 DIMM is currently the fastest memory and has one notchnear the center.RIMMs are named after Rambus Inc., the company that developed it. RIMMs are now slower than current DIMMs
Real mode uses 16 bit data path while protected mode uses 32 bit data path.
