Description
The MC-45D32DC721 is a 33,554,432 words by 72 bits DDR synchronous dynamic RAM module on which 18 pieces of 128M DDR SDRAM: µPD45D128842 are assembled.
These modules provide high density and large quantities of memory in a small space without utilizing the surfacemounting technology on the printed circuit board.
Decoupling capacitors are mounted on power supply line for noise reduction.
Features
• 33,554,432 words by 72 bits organization (ECC type)
• Clock frequency
• Fully Synchronous Dynamic RAM with all 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
• 2.5 V ± 0.2 V Power supply for VDD
• 2.5 V ± 0.2 V Power supply for VDDQ
• SSTL_2 compatible with all signals
• 4,096 refresh cycles / 64 ms
• Burst termination by Precharge command and Burst stop command
• 184-pin dual in-line memory module (Pin pitch = 1.27 mm)
• Registered type
• Serial PD
