... These address inputs are multiplexed for both read and write operations. Internally, the device is organized arrays each 18) for CY7C1512V18, and arrays each 36) for CY7C1514V18. Therefore, only 21 address inputs are needed to access the entire memory array of CY7C1512V18 and 20 address inputs for CY7C1514V18. These inputs are ignored when the appropriate port is deselected ...

... Functional Overview The CY7C1512V18, and CY7C1514V18 are synchronous pipelined Burst SRAMs with a read port and a write port. The read port is dedicated to read operations and the write port is dedicated to write operations. Data flows into the SRAM through the write port and flows out through the read port. These devices multiplex the address inputs to minimize the number of address pins required ...
