Reduced Latency DRAM (RLDRAM) is a type of specialty dynamic random-access memory (DRAM) with a SRAM-like interface originally developed by Infineon Technologies.
It is a high-bandwidth, semi-commodity, moderately low-latency (relative to contemporaneous SRAMs) memory targeted at embedded applications (such as computer networking equipment) requiring memories that have moderate costs and low latency (relative to commodity DRAM); and capacities greater than those offered by SRAMs.
[2] The first generation RLDRAM devices appeared in 1999, and were initially only fabricated by Infineon.
Later, Micron Technology was brought in as a development partner and second source for RLDRAM devices.
The second-generation RLDRAM II specification was announced by Infineon and Micron in 2003.
