Description
The IDT DDRII
TM
Burst of four SRAMs are high-speed synchro-
nous memories with a double-data-rate (DDR), bidirectional data port.
This scheme allows maximzation on the bandwidth on the data bus by
passing two data items per clock cycle. The address bus operates at
less than single data rate speeds,allowing the user to fan out addresses
and ease systemdesign while maintaining maximumperformance on
data transfers.
The DDRII has scalable output impedance on its data output bus
and echo clocks, allowing the user to tune the bus for low noise and high
performance.
All interfaces of the DDRII SRAMare HSTL, allowing speeds
beyond SRAMdevices that use any formof TTL interface. The inter-
face can be scaled to higher voltages (up to 1.9V) to interface with 1.8V
systems if necessary. The device has a V
DDQ
and
a separate Vref,
allowing the user to designate the interface operational voltage, inde-
pendent of the device core voltage of 1.8V V
DD.
The
output impedance
control allows the user to adjust the drive strength to adapt to a wide
range of loads and transmssion lines.

Notes
1) Represents 8 data signal lines for x8, 9 signal lines for x9, 18 signal lines for x18, and 36 signal lines for x36
2) Represents 19 address signal lines for x8 and x9, 20 address signal lines for x18, and 19 address signal lines for x36.
3) Represents 1 signal line for x9, 2 signal lines for x18, and four signal lines for x36. On x8 parts, the
BW
is a “nibble write” and there are 2
signal lines.
4) Represents 16 data signal lines for x8, 18 signal lines for x9, 36 signal lines for x18, and 72 signal lines for x36.
