CY7C1370D CY7C1372D Document #: 38-05555 Rev . *F Page 7 of 28 Introduction Functional Overview The CY7C1370D and C Y7C1372D are synchronous-pipeli ned Burst NoBL SRAMs designed specifically to eliminate wait states during Write/Read transi tions. All synchronous input s pass through input registers co ntrolled by the rising ed ge of the clock.
