Memory

The IDT70T631S15DD is a high-speed, high-capacity dynamic random access memory (DRAM) module from Integrated Device Technology (IDT). This memory module is typically used in servers, workstations, and storage applications. It provides an improved operating temperature range, faster write latency, and increased capacity compared to its predecessor, the IDT70T631S14DD.

The IDT70T631S15DD utilizes a double-data-rate (DDR) interface, meaning that data is transmitted to and from the module twice as fast as through a single-data-rate (SDR) interface. This allows for more efficient memory accesses, resulting in faster system performance. The DRAM is organized into 1,536-bit words, with each word containing eight bytes. The module is organized into 8K x 8-bit “pages”, with each page containing 16 words.

Data is stored in two separate SRAM (static random access memory) arrays on the module. Each array is organized as 4K x 16-bit words, with each word containing two bytes. When a memory access is requested, the appropriate words from both arrays are combined to form a single 8K x 16-bit word. This word is then split into two 4K x 8-bit words, which are then made available to the system.

This memory module is designed to operate over a temperature range of 0˚C to 70˚C. It is also designed to support a wide range of voltage levels, including 1.6V and 1.8V. It supports both 64-bit and 32-bit bus widths and is compatible with IDT\'s Synchronous DRAM (SDRAM) and Double Data Rate SDRAM (DDR SDRAM) technologies.

The IDT70T631S15DD also features an on-die power-management system. This allows the module to operate at lower power levels when system demand is low. This helps to improve system efficiency and save energy.

In summary, the IDT70T631S15DD is a high-speed, high-capacity memory module. It utilizes DDR interface technology, allowing for faster memory accesses and improved system performance. It is also designed to operate over a wide temperature range and a range of voltage levels. Finally, it features an on-die power-management system, which helps to save energy.
