IS61QDB251236A-250M3-TR 特徵

  • 512Kx36 and 1Mx18 configuration available.
  • On-chip Delay-Locked Loop (DLL) for wide data valid window.
  • Separate independent read and write ports with concurrent read and write operations.
  • Synchronous pipeline read with EARLY write operation.
  • Double Data Rate (DDR) interface for read and write input ports.
  • Fixed 2-bit burst for read and write operations.
  • Clock stop support.
  • Two input clocks (K and K#) for address and control registering at rising edges only. Two output clocks (C and C#) for data output control. Two echo clocks (CQ and CQ#) that are delivered simultaneously with data. +1.8V core power supply and 1.5, 1.8V VDDQ, used with 0.75, 0.9V VREF.
  • HSTL input and output levels.
  • Registered addresses, write and read controls, byte writes, data in, and data outputs.
  • Full data coherency.
  • Boundary scan using limited set of JTAG 1149.1 functions.
  • Byte write capability.
  • Fine ball grid array (FBGA) package: 13mmx15mm and 15mmx17mm body size 165-ball (11 x 15) array
  • Read address
  • Read enable
  • Write enable
  • Byte writes
  • Data-in for early writes The following are registered on the rising edge of the K# clock:
  • Write address
  • Byte writes

概觀

The synchronous, high-performance CMOS static random access memory (SRAM) devices. These SRAMs have separate I/Os, eliminating the need for high-speed bus turnaround. The rising edge of K clock initiates the read/write operation, and all internal operations are self-timed. Refer to the.
