DDR Memory Bank for High-Speed Capture Modules

Product Specifications

Technical details and manufacturing context for DDR Memory Bank

Definition

A DDR Memory Bank is a critical component within a High-Speed Capture Module that provides temporary, high-speed data storage for captured signals. It serves as the primary working memory where incoming data from sensors or inputs is buffered before processing or transfer to permanent storage. This component enables the module to handle rapid data acquisition rates by providing sufficient bandwidth and capacity for temporary data retention. The memory bank is built on a printed circuit board substrate with semiconductor memory chips, copper traces for signal routing, and a solder mask for protection. It is designed to meet JEDEC standards for DDR3 and DDR4 memory, with a data rate range of 1600 to 3200 MT/s, a memory capacity of 1 to 64 GB, and a CAS latency of 9 to 22 clock cycles. The module operates at a supply voltage of 1.2 to 1.5 V, depending on the DDR generation, and is rated for an operating temperature of 0 to 85 °C and a storage temperature of -40 to 100 °C. Physical dimensions include a module height of 18.75 to 31.25 mm, a standard width of 133.35 mm, and a pin count of 240 to 288 pins. The weight ranges from 10 to 20 grams. These parameters are reference ranges that must be confirmed for the specific model and application. The DDR Memory Bank is a component-level product, not a complete system, and its performance depends on the memory controller and system design. For procurement, verify that the module meets the required specifications and standards with the legal manufacturer or supplier.

Working Principle

The DDR Memory Bank operates using Double Data Rate (DDR) technology, which transfers data on both the rising and falling edges of the clock signal, effectively doubling the data transfer rate compared to single data rate memory. When the High-Speed Capture Module receives input signals, the data is temporarily stored in the memory bank's cells organized in rows and columns. The memory controller manages read/write operations, refresh cycles, and timing to ensure data integrity while maintaining the high throughput required for capture applications. The module's data rate, capacity, and latency determine its suitability for specific capture rates and buffering needs.
