The Kingston KCS-D3600/8 module has been developed to work with CISCO 3620 and 3640 routers. It provides additional memory to the devices, which is vital to streamline their functions while having a capacity of 8MB. As in the former case, this module is also easy to install and is aimed at improving the mounting performance of CISCO routers. Kingston, the manufacturer, has been in the computer hardware and accessories industry for over three decades; investors value the product-s performance and reliability.
