Its 300 MHz clock rate delivers back-to-back read and write operations with zero dead cycles between bus turns — the QDR-II architecture uses separate read and write data ports, so the bus never idles during direction changes. That matters in high-throughput data-path designs like network packet buffers, line cards, or test equipment where every clock cycle counts.
No official pin-compatible successor or second-source alternate is listed in the lifecycle record. For a drop-in replacement, search for a QDR-II SRAM with 36 Mbit density, 4M x 9 organization, and a 165-FBGA package — but verify the ball map against the Cypress package drawing before committing the board.
