Description
Qimonda 1-Gbit DDR Mobile-RAM is a high-speed CMOS,
dynamic random-access memory containing 1073741824
bits. It is internally configured as a quad-bank DRAM.
DDR Mobile-RAM is especially designed for mobile
applications. It operates from a 1.8 V power supply. Power
consumption in self refresh mode is drastically reduced by an
On-Chip Temperature Sensor (OCTS); it can further be
reduced by using the programmable Partial Array Self
Refresh (PASR). A conventional data-retaining Power-Down
(PD) mode is available as well as a non-data-retaining Deep
Power-Down (DPD) mode. For further power-savings the
clock may be stopped during idle periods.
DDR Mobile-RAM uses a double-data-rate architecture to
achieve high-speed operation. The double-data-rate
architecture is essentially a 2n pre fetch architecture, with an
interface designed to transfer two or four data words per clock
cycle at the I/O pins. A single READ or WRITE access for the
DRAM consists of a single 2n-bit wide, one clock cycle data
transfer at the internal DRAM core and two corresponding n-
bit wide, one-half clock cycle data transfers at the I/O pins.
The 1-Gbit DRAM is available in commercial (0 °C to +70 °C)
and extended (-25 °C to +85 °C) temperature ranges.
