They are organized as 131,072 words by 36 bits for K7P403622B and 262,144 words by 18 bits for K7P401822B, fabricated using Samsung's advanced CMOS technology. Single differential PECL level K clocks or Single ended or differential LVTTL clocks are used to initiate read/write operation and all internal operations are self-timed. At the rising edge of K clock, Addresses, Write Enables, Synchronous Select and Data Ins are registered internally. Data outs are updated from output registers at the next rising edge of K clock. An internal write data buffer allows write data to follow one cycle after addresses and controls. The package is 119(7x17) Ball Grid Array with balls on a 1.27mm pitch. Read Operation During read operations, addresses and controls are registered during the first rising edge of K clock and then the internal array is read between first and second edges of K clock. Data outputs are updated from output registers off the second rising edge of K clock. During consecutive read operations where the address is the same, the data output must be held constant without any glitches. This characteristic is because the SRAM will be read by devices that will operate slower than the SRAM frequency and will require multiple SRAM cycles to perform a single read operation. Write Operation(Late Write) During write operations, addresses and controls are registered at the first rising edge of K clock and data inputs are registered at the following rising edge of K clock. Write addresses and data inputs are stored in the data in registers until the next write operation, and only at the next write opeation are data inputs fully written into SRAM array. Byte write operation is supported using SW[a:d] and the timing of SW[a:d] is the same as the SW signal. Bypass Read Operation Bypass read operation occurs when the last write operation is followed by a read operation where write and read addresses are identical. For this case, data outputs are from the data in registers instead of SRAM array. Bypass read operation occurs on a byte to byte basis. If only one byte is written during a write operation but a read operation is required on the same address, a partial bypass read operation occurs since the new byte data is from the data in registers while the remaing bytes are from SRAM array. Sleep Mode Sleep mode is a low power mode initiated by bringing the asynchronous ZZ pin high. During sleep mode, all other inputs are ignored and outputs are brought to a High-Impedance state. Sleep mode current and output High-Z are guaranteed after the specified sleep mode enable time. During sleep mode the memory array data content is preserved. Sleep mode must not be initiated until after all pending operations have completed, since any pending operation will not guaranteed once sleep mode is initiated. Normal operations can be resumed by bringing the ZZ pin low, but only after the specified sleep mode recovery time. Mode Control There are two mode control select pins (M1 and M2) used to set the proper read protocol. This SRAM supports single clock pipelined operating mode. For proper specified device operation, M1 must be connected to VSS and M2 must be connected to VDD. These mode pins must be set at power-up and must not change during device operation. Power-Up/Power-Down Supply Voltage Sequence The following power-up supply voltage sequence is recommended: VSS, VDD, VDDQ, and VIN. VDD and VDDQ can be applied simultaneously, as long as VDDQ does not exceed VDD by more than 0.5V during power-up. The following power-down supply voltage removal sequence is recommended: VIN, VREF, VDDQ, VDD, VSS. VDD and VDDQ can be removed simultaneously, as long as VDDQ does not exceed VDD by more than 0.5V during power-down. -4- Jul. 2003 Rev 1.2 K7P403622B K7P401822B 128Kx36 & 256Kx18 SRAM TRUTH TABLE K ZZ G SS SW SWa SWb SWc SWd DQa DQb DQc DQd Operation X H X X X X X X X Hi-Z Hi-Z Hi-Z Hi-Z Power Down Mode.

This is to test the connectivity during manufacturing between SRAM, printed circuit board and other components. Internal data is not driven out of SRAM under JTAG control. In conformance with IEEE 1149.1, the SRAM contains a TAP controller, Instruction Register, Bypass Register and ID register. The TAP controller has a standard 16-state machine that resets internally upon power-up, therefore, TRST signal is not required. It is possible to use this device without utilizing the TAP. To disable the TAP controller without interfacing with normal operation of the SRAM, TCK must be tied to VSS to preclude mid level input. TMS and TDI are designed so an undriven input will produce a response identical to the application of a logic 1, and therefore can be left unconnected. But they may also be tied to VDD through a resistor. TDO should be left unconnected. JTAG Block Diagram JTAG Instruction Coding IR2 IR1 IR0 Instruction SRAM CORE M1 M2 TDI BYPASS Reg.
