Advanced Information GS82583ED18/36GK-675/625/550/500 288Mb SigmaQuad-IIIe™ Burst of 4 SRAM 260-Pin BGA Commercial Temp Industrial Temp Up to 675 MHz 1.3V VDD 1.2V, 1.3V, or 1.5V VDDQ Features Clocking and Addressing Schemes • • • • • • • • • • • • • • • • The GS82583ED18/36GK SigmaQuad-IIIe SRAMs are synchronous devices. They employ three pairs of positive and negative input clocks; one pair of master clocks, CK and CK, and two pairs of write data clocks, KD[1:0] and KD[1:0]. All six input clocks are single-ended; that is, each is received by a dedicated input buffer. 8Mb x 36 and 16Mb x 18 organizations available 675 MHz maximum operating frequency 675 MT/s peak transaction rate (in millions per second) 97 Gb/s peak data bandwidth (in x36 devices) Separate I/O DDR Data Buses Non-multiplexed SDR Address Bus One operation - Read or Write - per clock cycle Burst of 4 Read and Write operations 3 cycle Read Latency 1.3V nominal core voltage 1.2V, 1.3V, or 1.5V HSTL I/O interface Configurable ODT (on-die termination) ZQ pin for programmable driver impedance ZT pin for programmable ODT impedance IEEE 1149.1 JTAG-compliant Boundary Scan 260-pin, 14 mm x 22 mm, 1 mm ball pitch, 6/6 RoHS- compliant BGA package SigmaQuad-IIIe™ Family Overview CK and CK are used to latch address and control inputs, and to control all output timing. KD[1:0] and KD[1:0] are used solely to latch data inputs. Each internal read and write operation in a SigmaQuad-IIIe B4 SRAM is four times wider than the device I/O bus. An input data bus de-multiplexer is used to accumulate incoming data before it is simultaneously written to the memory array. An output data multiplexer is used to capture the data produced from a single memory array read and then route it to the appropriate output drivers as needed. Therefore, the address field of a SigmaQuad-IIIe B4 SRAM is always two address pins less than the advertised index depth (e.g. the 16M x 18 has 4M addressable index). SigmaQuad-IIIe SRAMs are the Separate I/O half of the SigmaQuad-IIIe/SigmaDDR-IIIe family of high performance SRAMs. Although very similar to GSI's second generation of networking SRAMs (the SigmaQuad-II/SigmaDDR-II family), these third generation devices offer several new features that help enable significantly higher performance.

Power supplies must power down simultaneously, or in the reverse sequence. After power supplies power up, the following start-up sequence must be followed. Step 1 (Recommended, but not required): Assert RST High for at least 1ms. While RST is asserted high: • The DLL is disabled. • The states of R, and W control inputs are ignored. Note: If possible, RST should be asserted High before input clocks begin toggling, and remain asserted High until input clocks are stable and toggling within specification, in order to prevent unstable, out-of-spec input clocks from causing trouble in the SRAM. Step 2: Begin toggling input clocks. After input clocks begin toggling, but not necessarily within specification: • Q are placed in the non-Read state, and remain so until the first Read operation. • QVLD are driven Low, and remain so until the first Read operation. • CQ, CQ begin toggling, but not necessarily within specification. Step 3: Wait until input clocks are stable and toggling within specification. Step 4: De-assert RST Low (if asserted High). Step 5: Wait at least 160K (163,840) cycles. During this time: • Driver and ODT impedances are calibrated. Can take up to 160K cycles. Note: The DLL pin may be asserted High or de-asserted Low during this time. If asserted High, DLL synchronization begins immediately after the driver and ODT impedances are calibrated. If de-asserted Low, DLL synchronization begins after the DLL pin is asserted High (see Step 6). In either case, Step 7 must follow thereafter. Step 6: Assert DLL pin High (if de-asserted Low). Step 7: Wait at least 64K (65,536) cycles for the DLL to lock. After the DLL has locked: • CQ, CQ begin toggling within specification. Step 8: Begin initiating Read and Write operations. Reset Usage Although not generally recommended, RST may be asserted High at any time after completion of the initial power-up sequence described above, to reset the SRAM control logic to its initial power-on state. However, whenever RST is subsequently de-asserted Low (as in Step 4 above), Steps 5~7 above must be followed before Read and Write operations are initiated. Note: Memory array content may be perturbed/corrupted when RST is asserted High. Rev: 1.04 7/2015 6/26 Specifications cited are subject to change without notice. For latest documentation see http://www.gsitechnology.com. © 2014, GSI Technology Advanced Information GS82583ED18/36GK-675/625/550/500 DLL Operation A DLL is implemented in these devices to control all output timing. It uses the CK input clock as a source, and is enabled when all of the following conditions are met: 1. RST is de-asserted Low, and 2. The DLL pin is asserted High, and 3. CK cycle time tKHKH (max), as specified in the AC Timing Specifications section. Once enabled, the DLL requires 64K stable clock cycles in order to lock/synchronize properly. When the DLL is enabled, it aligns output clocks and read data to input clocks, and it generates all mid-cycle output timing. See the Output Timing section for more information. The DLL can tolerate changes in input clock frequency due to clock jitter (i.e. such jitter will not cause the DLL to lose lock/ synchronization), provided the cycle-to-cycle jitter does not exceed 200ps (see “tKJITcc” in the AC Timing Specifications section for more information). However, the DLL must be resynchronized (i.e. disabled and then re-enabled) whenever the nominal input clock frequency is changed. The DLL is disabled when any of the following conditions are met: 1. RST is asserted High, or 2. The DLL pin is de-asserted Low, or 3. CK is stopped for at least 30ns, or CK cycle time 30ns.

Specifically: CK latches all address (SA) inputs. CK latches all control (R, W) inputs. KD[1:0] and KD[1:0] latch particular write data (D) inputs, as follows: • KD0 and KD0 latch D[17:0] in x36, and D[8:0] in x18. • KD1 and KD1 latch D[35:18] in x36, and D[17:9] in x18. Output Timing These devices provide two pairs of positive and negative output clocks (aka “echo clocks”), CQ[1:0] & CQ[1:0], whose timing is tightly aligned with read data in order to enable reliable source-synchronous data transmission. These devices utilize a DLL to control output timing. When the DLL is enabled, it generates 0 and 180 phase clocks from CK that control read data output clock (CQ, CQ), read data (Q), and read data valid (QVLD) output timing, as follows: • CK+0 generates CQ[1:0], CQ[1:0], Q1 active, and Q2 inactive. • .CK+180 generates CQ[1:0], CQ[1:0], Q1 inactive, Q2 active, and QVLD active/inactive. Note: Q1 and Q2 indicate the first and second pieces of read data transferred in any given clock cycle during Read operations. When the DLL is enabled, CQ is aligned to CK. See the AC Timing Specifications for more information. CQ[1:0] and CQ[1:0] align with particular Q and QVLD outputs, as follows: • CQ0 and CQ0 align with Q[17:0], QVLD0 in x36 devices, and Q[8:0], QVLD0 in x18 devices. • CQ1 and CQ1 align with Q[35:18], QVLD1 in x36 devices, and Q[17:9], QVLD0 in x18 devices.

Driver impedance is programmed by connecting an external resistor RQ between the ZQ pin and VSS. Driver impedance is set to the programmed value within 160K cycles after input clocks are operating within specification and RST is de-asserted Low. It is updated periodically thereafter to compensate for temperature and voltage fluctuations in the system.

ODT Impedance Control Programmable ODT Impedance is implemented on the following input signals: • CK, CK, KD, KD, SA, R, W, D. ODT impedance is programmed by connecting an external resistor RT between the ZT pin and VSS.

The mismatch between RINL and RINH is less than 10%, guaranteed by design. 4. All ODT is disabled during JTAG EXTEST and SAMPLE-Z instructions. Note: When ODT impedance is enabled on a particular input, that input should always be driven High or Low; it should never be tri-stated (i.e., in a High- Z state). If the input is tri-stated, the ODT will pull the signal to VDDQ / 2 (i.e., to the switch point of the diff-amp receiver), which could cause the receiver to enter a meta-stable state and consume more power than it normally would. This could result in the device’s operating currents being higher. Rev: 1.04 7/2015 9/26 Specifications cited are subject to change without notice.

As such, it limits Period Jitter (i.e. the maximum variation in clock cycle time from nominal) to 30ps. And as such, it limits Absolute Jitter (i.e. the maximum variation in clock rising edge from its nominal position) to 15ps. 5. The device can tolerated C2C Jitter greater than 60ps, up to a maximum of 200ps. However, when using a device from a particular speed grade, tKHKH (min) of that speed grade must be derated (increased) by half the difference between the actual C2C Jitter and 60ps. For example, if the actual C2C Jitter is 100ps, then tKHKH (min) for the -675 speed grade is derated to 1.5ns (1.48ns + 0.5*(100ps - 60ps)). 6.

This test mode is intended to provide a mechanism for testing the interconnect between master (processor, controller, etc.), ECCRAM, other components, and the printed circuit board. In conformance with a subset of IEEE std. 1149.1, these devices contain a TAP Controller and multiple TAP Registers. The TAP Registers consist of one Instruction Register and multiple Data Registers. The TAP consists of the following four signals: Pin Pin Name I/O Description TCK Test Clock I Induces (clocks) TAP Controller state transitions. TMS Test Mode Select I Inputs commands to the TAP Controller. Sampled on the rising edge of TCK. TDI Test Data In I Inputs data serially to the TAP Registers. Sampled on the rising edge of TCK. TDO Test Data Out O Outputs data serially from the TAP Registers. Driven from the falling edge of TCK. Concurrent TAP and Normal ECCRAM Operation According to IEEE std. 1149.1, most public TAP Instructions do not disrupt normal device operation. In these devices, the only exceptions are EXTEST and SAMPLE-Z. See the Tap Registers section for more information. Disabling the TAP When JTAG is not used, TCK should be tied Low to prevent clocking the ECCRAM. TMS and TDI should either be tied High through a pull-up resistor or left unconnected. TDO should be left unconnected.

State transitions are controlled by TMS and occur on the rising edge of TCK. The TAP Controller enters the Test-Logic Reset state in one of two ways: 1. At power up. 2. When a logic 1 is applied to TMS for at least 5 consecutive rising edges of TCK. The TDI input receiver is sampled only when the TAP Controller is in either the Shift-IR state or the Shift-DR state. The TDO output driver is enabled only when the TAP Controller is in either the Shift-IR state or the Shift-DR state.

They are divided into two groups: Instruction Registers (IR), which are manipulated via the IR states in the TAP Controller, and Data Registers (DR), which are manipulated via the DR states in the TAP Controller. Instruction Register (IR - 3 bits) The Instruction Register stores the various TAP Instructions supported by ECCRAM. It is loaded with the IDCODE instruction (logic 001) at power-up, and when the TAP Controller is in the Test-Logic Reset and Capture-IR states. It is inserted between TDI and TDO when the TAP Controller is in the Shift-IR state, at which time it can be loaded with a new instruction. However, newly loaded instructions are not executed until the TAP Controller has reached the Update-IR state. The Instruction Register is 3 bits wide, and is encoded as follows: Code (2:0) Instruction Description EXTEST Loads the logic states of all signals composing the ECCRAM I/O ring into the Boundary Scan Register when the TAP Controller is in the Capture-DR state, and inserts the Boundary Scan Register between TDI and TDO when the TAP Controller is in the Shift-DR state. Also transfers the contents of the Boundary Scan Register associated with output signals (Q, QVLD, CQ, CQ) directly to their corresponding output pins. However, newly loaded Boundary Scan Register contents do not appear at the output pins until the TAP Controller has reached the Update-DR state. Also disables all ODT. See the Boundary Scan Register description for more information. IDCODE Loads a predefined device- and manufacturer-specific identification code into the ID Register when the TAP Controller is in the Capture-DR state, and inserts the ID Register between TDI and TDO when the TAP Controller is in the Shift-DR state. See the ID Register description for more information. 010 SAMPLE-Z Loads the logic states of all signals composing the ECCRAM I/O ring into the Boundary Scan Register when the TAP Controller is in the Capture-DR state, and inserts the Boundary Scan Register between TDI and TDO when the TAP Controller is in the Shift-DR state. Also disables all ODT. Also forces Q output drivers to a High-Z state. See the Boundary Scan Register description for more information. 011 PRIVATE Reserved for manufacturer use only. 100 SAMPLE Loads the logic states of all signals composing the ECCRAM I/O ring into the Boundary Scan Register when the TAP Controller is in the Capture-DR state, and inserts the Boundary Scan Register between TDI and TDO when the TAP Controller is in the Shift-DR state. See the Boundary Scan Register description for more information. 101 PRIVATE Reserved for manufacturer use only. 110 PRIVATE Reserved for manufacturer use only. 111 BYPASS Loads a logic 0 into the Bypass Register when the TAP Controller is in the Capture-DR state, and inserts the Bypass Register between TDI and TDO when the TAP Controller is in the Shift-DR state. See the Bypass Register description for more information. 000 001 Rev: 1.04 7/2015 21/26 Specifications cited are subject to change without notice. For latest documentation see http://www.gsitechnology.com. © 2014, GSI Technology Advanced Information GS82583ED18/36GK-675/625/550/500 Bypass Register (DR - 1 bit) The Bypass Register is one bit wide, and provides the minimum length serial path between TDI and TDO. It is loaded with a logic 0 when the BYPASS instruction has been loaded in the Instruction Register and the TAP Controller is in the Capture-DR state. It is inserted between TDI and TDO when the BYPASS instruction has been loaded into the Instruction Register and the TAP Controller is in the Shift-DR state. ID Register (DR - 32 bits) The ID Register is loaded with a predetermined device- and manufacturer-specific identification code when the IDCODE instruction has been loaded into the Instruction Register and the TAP Controller is in the Capture-DR state. It is inserted between TDI and TDO when the IDCODE instruction has been loaded into the Instruction Register and the TAP Controller is in the Shift-DR state. The ID Register is 32 bits wide, and is encoded as follows: See BSDL Model (31:12) GSI ID (11:1) Start Bit (0) XXXX XXXX XXXX XXXX XXXX 0001 1011 001 1 Bit 0 is the LSB of the ID Register, and Bit 31 is the MSB. When the ID Register is selected, TDI serially shifts data into the MSB, and the LSB serially shifts data out through TDO. Boundary Scan Register (DR - 129 bits) The Boundary Scan Register is equal in length to the number of active signal connections to the ECCRAM (excluding the TAP pins) plus a number of place holder locations reserved for functional and/or density upgrades. It is loaded with the logic states of all signals composing the ECCRAM’s I/O ring when the EXTEST, SAMPLE, or SAMPLE-Z instruction has been loaded into the Instruction Register and the TAP Controller is in the Capture-DR state. It is inserted between TDI and TDO when the EXTEST, SAMPLE, or SAMPLE-Z instruction has been loaded into the Instruction Register and the TAP Controller is in the Shift-DR state. Additionally, the contents of the Boundary Scan Register associated with the ECCRAM outputs (Q, QVLD, CQ, CQ) are driven directly to the corresponding ECCRAM output pins when the EXTEST instruction is selected. However, after the EXTEST instruction has been selected, any new data loaded into Boundary Scan Register when the TAP Controller is in the Shift-DR state does not appear at the output pins until the TAP Controller has reached the Update-DR state. The value captured in the boundary scan register for NU pins is determined by the external pin state. The value captured in the boundary scan register for NC pins is 0 regardless of the external pin state. The value captured in the Internal Cell (Bit 129) is 1. Output Driver State During EXTEST EXTEST allows the Internal Cell (Bit 129) in the Boundary Scan Register to control the state of Q drivers. That is, when Bit 129 = 1, Q drivers are enabled (i.e., driving High or Low), and when Bit 129 = 0, Q drivers are disabled (i.e., forced to High-Z state). See the Boundary Scan Register section for more information. ODT State During EXTEST and SAMPLE-Z ODT on all inputs is disabled during EXTEST and SAMPLE-Z.
