AUTO SELF REFRESH (ASR)
Mode register MR2[6] is used to disable/enable the ASR function. When ASR is disabled,
the self refresh mode’s refresh rate is assumed to be at the normal 85°C limit (some-
times referred to as 1x refresh rate). In the disabled mode, ASR requires the user to en-
sure the DRAM never exceeds a case temperature ( T
C
) of 85°C while in self refresh, un-
less the user enables the SRT function when T
C
is between 85°C and 95°C.
Enabling ASR assumes the DRAM self refresh rate is changed automatically from 1x to
2x when T
C
exceeds 85°C. This enables the user to operate the DRAM beyond the stand-
ard 85°C limit up to the optional extended temperature range of 95°C while in self re-
fresh mode.
The standard self refresh current test specifies test conditions for normal T
C
(85°C) only,
meaning that if ASR is enabled, the standard self refresh current specifications do not
apply (see Extended Temperature Usage (page 183)).
SELF REFRESH TEMPERATURE (SRT)
Mode register MR2[7] is used to disable/enable the SRT function. When SRT is disabled,
the self refresh mode’s refresh rate is assumed to be at the normal 85°C limit (some-
times referred to as 1x refresh rate). In the disabled mode, SRT requires the user to en-
sure the DRAM never exceeds a T
C
of 85°C while in self refresh mode, unless the user
enables ASR.
When SRT is enabled, the DRAM self refresh is changed internally from 1x to 2x, regard-
less of T
C
. This enables the user to operate the DRAM beyond the standard 85°C limit up
to the optional extended temperature range of 95°C while in self refresh mode. The
standard self refresh current test specifies test conditions for normal T
C
(85°C) only,
meaning that if SRT is enabled, the standard self refresh current specifications do not
apply (see Extended Temperature Usage (page 183)).
