The HYB39S16160CT-6/-7 are high speed dual bank Synchronous DRAM’s based on SIEMENS
0.25µm process and organized as 2 banks x 512kbit x 16. These synchronous devices achieve high
speed data transfer rates up to 166 MHz by employing a chip architecture that prefetches multiple
bits and then synchronizes the output data to a system clock. The chip is fabricated with SIEMENS’
advanced 16MBit DRAM process technology.
The device is designed to comply with all JEDEC standards set for synchronous DRAM products,
both electrically and mechanically. All of the control, address, data input and output circuits are
synchronized with the positive edge of an externally supplied clock.
Operating the two memory banks in an interleaved fashion allows random access operation to occur
at higher rate than is possible with standard DRAMs. A sequential and gapless data rate of up to 166
MHz is possible depending on burst length, CAS latency and speed grade of the device.
Auto Refresh (CBR) and Self Refresh operation are supported. These devices operate with a single
3.3V +/- 0.3V power supply and are available in TSOPII packages.
These Synchronous DRAM devices are available with LV-TTL interfaces.

Operation Definition
All of SDRAM operations are defined by states of control signals CS, RAS, CAS, WE, and DQM at
the positive edge of the clock. The following list shows the most important operation commands.

Mode Register
For application flexibility, a CAS latency, a burst length, and a burst sequence can be
programmed in the SDRAM mode register. The mode set operation must be done before any
activate command after the initial power up. Any content of the mode register can be altered by re-
executing the mode set command. Both banks must be in precharged state and CKE must be high
at least one clock before the mode set operation. After the mode register is set, a Standby or NOP
command is required. Low signals of RAS, CAS, and WE at the positive edge of the clock activate
the mode set operation. Address input data at this timing defines parameters to be set as shown in
the following table.
