For a 36-bit word, that's 2.7 GB/s of read-write bandwidth, which puts it squarely in networking packet buffers, telecom line cards, and high-end test equipment where the bus is the bottleneck, not the core logic. ## 512K x 36 organization — why the width matters The 36-bit word width (with four spare bits beyond a 32-bit word) is common in networking designs that carry parity or ECC metadata alongside the data bus. A 512K depth means 512K unique addresses, so the buffer can hold 512K 36-bit entries — enough for several maximum-size Ethernet frames or a full ATM cell queue. The DDR II+ interface eliminates the dead cycles between read and write turns that first-generation DDR SRAMs needed, keeping the bus fully utilized in mixed-read-write traffic patterns. Cypress (now Infineon) lists the CY7C1320KV18-300BZXC as Obsolete. That means new-production orders through franchised distribution are not available. This is a last-time-buy / NRND situation — the available pool is fixed and shrinking. ## Package and supply — layout constraints Surface-mount only, no socketed option.","metaTitle":"CY7C1320KV18-300BZXC Cypress 18Mbit DDR II SRAM, 300 MHz","metaDescription":"CY7C1320KV18-300BZXC Cypress 18Mbit DDR II+ SRAM, 300 MHz, 512Kx36, 165-FBGA, 1.8V.
