S ELF
Self -refresh mode is entered by issuing a REF S command (/CS=/RA S=/CAS =L ,/WE =H,C KE =L ).
Once the self-refresh is initiated, it is maintained as long as C KE is kept low. During the self-
refresh mode, CK E i s asynchronous and the only enable input , all other inputs including CL K a re
disabled and ignored, so that power consumption dueto synchronous inputs is saved. T o exit the
self-refresh, supplying stable CLK inputs, asserting DESEL or NOP command and then asserting
CK E f or longer than tX SNR/ tXSRD.
