Description
Symbol CK, CK# Type Input
4Mx32 DDR SDRAM
EM6A9320
Table 1. Pin Details of EM6A9320 Description Differential Clock: CK, CK# are driven by the system clock.All SDRAM input commands are sampled on the positive edge of CK.Both CK and CK# increment the internal burst counter and controls the output registers.Clock Enable: CKE activates (HIGH) and deactivates (LOW) the CK signal.If CKE goes low synchronously with clock, the internal clock is suspended from the next clock cycle and the state o
