R-DIMM Series

R-DIMM i.e. Registered DIMM is positioned in the general desktop computer market, which means that the address and control signals do not pass through the buffer, without any timing adjustment (buffer delay is there), and directly connect to the DRAM chip on the memory module.

IMS R-DIMM DRAM Series consists of the top-grade DRAM chips featuring a high throughput transfer rate with elaborate circuit layout to enhance signal integrity and extremely low noise interference. In order to fulfil all memory demand of different computer designs, IMS R-DIMM series provides all DDR3/DDR3L, DDR4 and DDR5 memory modules which will perfectly support any computer operation.

The ISCS681G Series which provides 16 GB to 512 GB NAND capacity and supports XLC setting to configure as 5 GB to 160 GB capacity is similar to SLC grade performance.
