SDRAM UDIMM

Netlist SDRAM Unbuffered DIMM (UDIMM) offers a broad range of cost-effective solutions for high speed, high reliability needs.  An Unbuffered DIMM is a module that does not have a register. These modules are often utilized in small systems that include one or two DIMM modules per channel. The chipset Address/Command signals directly drive all the DRAM chips without compromising on the bus speed.  UDIMMs are usually installed in desktops and workstations that have just two or four DIMM slots in the system. Unbuffered DIMMs can be configured either with ECC or without ECC.
