Part identity and what it does
The Infineon CY7C1041G18-15BVXI is a 4 Mbit asynchronous SRAM organized as 256K x 16 bits, with a 15 ns access time. It operates from a 1.65 V to 2.2 V supply.
15 ns access time — what it means on the bus
A 15 ns access time means the SRAM delivers valid data within 15 ns of the address being stable. For a 1.65 V to 2.2 V supply, that timing leaves slack for address decoding and trace delay.
