CY7C1350G Document #: 38-05524 Rev . *F Page 4 of 15 Functional Overview The CY7C1350G is a synchronous-pipelin ed Burst SRAM designed specifically to el iminate wait states during Write/Read transitions. All synchronous inputs pass through input registers controlled by the rising edge of the clock.
