Electrical Characteristics
Maximum and Typical Standby Currents
The following table and figure refer to the maximum and typical standby currents for the
MT45W1MW16BDGB device. The typical values shown in Figure 23 are measured with
the default on-chip temperature sensor control enabled. The maximum values shown in
Table 9 are measured with the relevant TCR bits set in the configuration register.

Notes:
1. For RCR[6:5] = 00b (default) refer to Figure 23, Typical Refresh Current vs. Temperature
(I TCR ) for typical values.
2. In order to achieve low standby current, all inputs must be driven to V CC Q or V SS . I SB might
be slightly higher for up to 500ms after power-up, after changes to the PAR array portion,
or when entering standby mode.
3. TCR values for 85°C are 100 percent tested. TCR values for 15°C and 45°C are sampled only.
4. Typical I SB currents for each PAR setting with the appropriate TCR selected, or temperature
sensor enabled.
