GENERAL DESCRIPTION
The P16M648YA7 and P32M6416YA7 is a high
performance dynamic random-access 256MB module,
organized in a x64 configuration, and utilize quad bank
architecture with a synchronous interface. All signals are
registered on the positive edge of the clock signals CK0
through CK3. Read and write accesses to the SDRAM are
burst oriented; accesses start at a location and continue
for a programmed number of locations in a sequence.
Accesses begin with an ACTIVE command, which is
followed by a READ or WRITE command.

SERIAL PRESENCE-DETECT OPERATION - This module incorporates Serial Presence-Detect (SPD) . The SPD function is
implemented using a 2,048 bit EEPROM, containing 256 bytes of nonvolatile storage. The first 128 bytes can be programmed
by SpecTek to identify the module type and various DRAM organization and timing parameters. The remaining 128 bytes of
storage are available for use by the customer. System READ/WRITE operations between the master (system logic) and the
slave EEPROM device (DIMM) occur via a standard IIC bus using the DIMM’s SCL (clock) and SDA (data) signals, together
with SA(2:0), which provide 8 unique DIMM/EEPROM addresses.
SPD CLOCK AND DATA CONVENTIONS - Data states on the SDA line can change only during SCL LOW. SDA state
changes during SCL HIGH are reserved for indicating start and stop conditions (Figures 1 and 2).
SPD START CONDITION - All commands are preceded by the start condition, which is a HIGH to LOW transition of SDA
when SCL is HIGH. The serial PD device continuously monitors the SDA and SCL lines for the start condition and will not
respond to any command until this condition has been met.
SPD STOP CONDITION - All communications are terminated by a stop condition, which is a LOW to HIGH transition of SDA
when SCL is HIGH. The stop condition also places the serial PD device into standby power mode.
SPD ACKNOWLEDGE - Acknowledge is a software convention used to indicate successful data transfers. The transmitting
device, either master or slave, will release the bus after transmitting eight bits of data (Figure 3). The PD device will always
respond with an acknowledge after recognition of a start condition and its slave address. If both the device and a write
operation have been selected, the PD device will respond with an acknowledge after the receipt of each subsequent eight bit
word. In the read mode the PD device will transmit eight bits of data, release the SDA line and monitor the line for an
acknowledge. If an acknowledge is not detected, the slave will terminate further data transmissions and await the stop
condition to return to standby power mode.

NOTES: 1. The SPD EEPROM WRITE cycle time (tWR) is the time from a valid stop condition of a WRITE sequence to the
end of the EEPROM internal erase/program cycle. During the WRITE cycle the EEPROM bus interface circuit is disabled, SDA
remains HIGH due to pull-up resistor, and the EEPROM does not respond to its slave address.
