IS43TR81280B : - JEDEC Standard Symbol Type Function CK, CK# CKE CS# ODT RAS#. CAS#. WE# DM, (DMU), (DML) BA0 - BA2 A0 - A13 A10 / AP A12 / BC# RESET# DQ(DQL, DQU) Input Input Input Input Input Clock: CK and CK# are differential clock inputs. All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK#. Clock Enable: CKE HIGH activates, and CKE Low deactivates, internal clock signals and device input buffers and output drivers. Taking CKE Low provides Precharge Power-Down and SelfRefresh operation (all banks idle), or Active Power-Down (row Active in any bank). CKE is asynchronous for Self-Refresh exit. After VREFCA and VREFDQ have become stabl.
