256MB 184 PIN DDR333 DDR SDRAM DIMM With 32Mx8 2.5VOLT JM334D643A-60 Description Placement The JM334D643A-60 is a 32M x 64bits Double Data Rate SDRAM high density for DDR333. The JM334D643A-60 consists of 8pcs CMOS 32Mx8 bits Double Data Rate SDRAMs in 66 pin TSOP-II 400mil packages and a 2048 bits serial EEPROM on a 184-pin printed circuit board. The JM334D643A-60 is a Dual In-Line Memory Module and is intended for mounting into 184-pin edge connector sockets. A Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges of DQS. Range of operation frequencies, programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance B memory system applications. Features • Power supply: VDD: 2.5V ± 0.2V, VDDQ: 2.5V ± C 0.2V • Max clock Freq: 166MHZ. • Double-data-rate architecture; two data transfers per D I clock cycle • H Differential clock inputs(CK and /CK) • Burst Mode Operation. • Auto and Self Refresh. • • Data I/O transactions on both edge of data strobe. G F E Edge aligned data output, center aligned data input. • Serial Presence Detect (SPD) with serial EEPROM • SSTL-2 compatible inputs and outputs. • MRS cycle with address key programs.

Includes ± 25mV margin for DC offset on VREF, and a combined total of ± 50mV margin for all AC noise and DC offset on VREF, bandwidth limited to 20MHz. The DRAM must accommodate DRAM current spikes on VREF and internal DRAM noise coupled. TO VREF, both of which may result in VREF noise. VREF should be de-coupled with an inductance of <=3nH. 2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF, and must track variations in the DC level of VREF 3. VID is the magnitude of the difference between the input level on CK and the input level on /CK. 4. These parameters should be tested at the pin on actual components and may be checked at either the pin or the pad in simulation. The AC and DC input specifications are relative to a VREF envelop that has been bandwidth limited to 200MHZ. 5. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in the dc level of the same.

Maximum burst refresh of 8 2. The specific requirement is that DQS be valid (High or Low) on or before this CK edge. The case shown (DQS going from High_Z to logic Low) applies when no writes were previously in progress on the bus. If a previous write was in progress, DQS could be High at this time, depending on tDQSS. 3. The Maximum limit for this parameter is not a device limit. The device will operate with a great value for this parameter, but system performance (bus turnaround) will degrade accordingly. 4. For registered DINNs, tCL and tCH are >= 45% of the period including both the half period jitter (tJIT(HP) ) of the PLL and the half period jitter due to crosstalk (tJIT(crosstalk)) on the DIMM.

(@EMRS/MRS EMRS/ MRS can be issued only at all banks precharge state. Auto refresh functions are same as the CBR refresh of DRAM. The automatic precharge without row precharge command is meant by "Auto". Auto/self refresh can be issued only at all banks precharge state. BA0 ~ BA1: Bank select addresses. If both BA0 and BA1 are "Low" at read, write, row active and precharge, bank A is selected. If both BA0 is "High" and BA1 is "Low" at read, write, row active and precharge, bank B is selected. If both BA0 is "Low" and BA1 is "High" at read, write, row active and precharge, bank C is selected. If both BA0 and BA1 are "High" at read, write, row active and precharge, bank D is selected. If A10/AP is "High" at row precharge, BA0 and BA1 are ignored and all banks are selected. During burst write with auto precharge, new read/write command cannot be issued. Another bank read/write command can be issued after the end of burst.. New row active of the associated bank can be issued at tRP after the end of burst. Burst stop command is valid at every burst length. DM sampled at the rising and falling edges of the DQS and Data-in is masked at the both edges (Write DM latency is 0). This combination is not defined for any function, which means "No Operation (NOP)" in DDR SDRAM.
