PRELIMINARY DATA SHEET  
MOS INTEGRATED CIRCUIT  
EDD1204ALTA, EDD1208ALTA, EDD1216ALTA  
128 M-bit Synchronous DRAM with Double Data Rate  
(4-bank, SSTL_2)  
Description  
The EDD1204ALTA, EDD1208ALTA, EDD1216ALTA are high-speed 134,217,728 bits synchronous dynamic  
random-access memories, organized as 8,388,608x4x4, 4,194,304x8x4, 2,097,152x16x4 (word x bit x bank),  
respectively.  
The synchronous DRAMs use Double Data Rate (DDR) where data bandwidth is twice of regular synchronous  
DRAM.  
The synchronous DRAM is compatible with SSTL_2 (Stub Series terminated Logic for 2.5 V).  
The synchronous DRAM is packaged in 66-pin Plastic TSOP (II).  
Features  
Fully Synchronous Dynamic RAM with all input signals except DM, DQS and DQ referenced to a positive clock edge  
Double Data Rate interface  
Differential CLK (/CLK) input  
Data inputs and DM are synchronized with both edges of DQS  
Data outputs and DQS are synchronized with a cross point of CLK and /CLK  
Quad internal banks operation  
Possible to assert random column address in every clock cycle  
Programmable Mode register set  
/CAS latency (2, 2.5)  
Burst length (2, 4, 8)  
Wrap sequence (Sequential / Interleave)  
Automatic precharge and controlled precharge  
CBR (Auto) refresh and self refresh  
x4, x8, x16 organization  
Byte write control (x4, x8) by DM  
Byte write control (x16) by LDM and UDM  
2.5 V ± 0.2 V Power supply for VDD  
2.5 V ± 0.2 V Power supply for VDDQ  
Maximum clock frequency up to 133 MHz  
SSTL_2 compatible with all signals  
4,096 refresh cycles/64 ms  
66-pin Plastic TSOP (II) (10.16 mm (400))  
Burst termination by Precharge command and Burst stop command
