QDR II+ SRAM — 144Mbit at 450 MHz clock
The CY7C2665KV18-450BZI is a 144Mbit synchronous SRAM using QDR II+ architecture, organized as 4M x 36. The 450 MHz clock rate delivers 900 MHz data rate on the read and write ports simultaneously — the QDR II+ interface eliminates the dead cycles of a common I/O bus, so the memory keeps the pipeline full on back-to-back transactions. Operating from a 1.7V to 1.9V core supply, the device draws its power from a low-voltage rail typical of high-performance FPGAs and ASICs. The parallel interface means all address and data lines route point-to-point to the controller; no serialization latency.
Active lifecycle — sourcing for production and repair
Infineon lists this part as Active. The base product number CY7C2665 covers the family; the suffix -450BZI encodes the 450 MHz speed grade, industrial temperature, and FBGA package. Lot traceability and date-code consistency are verified on each shipment — the laser-etched marking on the package top is cross-checked against Infineon's plant records for the reported date code.
