The Cypress CY14V256LA is a fast static RAM, with a nonvolatile element in each memory cell. The memory is organized as 32 K bytes of 8 bits each. 組み込み不揮発性エレメントには、QuantumTrap テクノロジが組み込まれており、世界でも最高レベルの信頼性を誇る不揮発性メモリを作り上げます。回数に制限のないリードとライトをSRAMで可能にする一方、それとは別に不揮発性データを不揮発性エレメントに保持できるようにしています。Data transfers from the SRAM to the nonvolatile elements (the STORE operation) takes place automatically at power down. On power-up, data is restored to the SRAM (the RECALL operation) from the nonvolatile memory. Both the STORE and RECALL operations are also available under software control.

Dear valued customer,

Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you. 

Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
