Product Summary

The MT47H128M16RT-25E:C is a DDR2 SDRAM. The MT47H128M16RT-25E:C uses a double data rate architecture to achieve high-speed operation. The double data rate architecture of the MT47H128M16RT-25E:C is essentially a 4n-prefetch architecture, with an interface designed to transfer two data words per clock cycle at the I/O balls. A single read or write access for the MT47H128M16RT-25E:C effectively consists of a single 4n-bit-wide, one-clock-cycle data transfer at the internal DRAM core and four corresponding n-bit-wide, one-half-clock-cycle data transfers at the I/O balls.

Parametrics

MT47H128M16RT-25E:C absolute maximum ratings: (1)VDD supply voltage relative to VSS, VDD: –1.0 to 2.3 V; (2)VDDQ supply voltage relative to VSSQ, VDDQ: –0.5 to 2.3 V; (3)VDDL supply voltage relative to VSSL, VDDL: –0.5 to 2.3 V; (4)Voltage on any ball relative to VSS, VIN, VOUT: –0.5 to 2.3 V; (5)Input leakage current, II: –5 to 5 μA; (6)Output leakage current, IOZ: –5 to 5 μA; (7)VREF leakage current, IVREF: –2 to 2 μA.
