This DRAM was commonly used in older computing and industrial applications requiring moderate-speed memory.

Application Scenarios & Design Considerations

1M x 4 Bit FPM DRAM 3.3 V 60 ns

Alternative Part Number

  • AS4C4M4SA-60TCN --: 4M x 4-bit 60ns asynchronous DRAM in a 20-pin SOJ package, functionally equivalent to the HYB314400BJ-60 and available as a direct drop-in replacement.
  • IS41C4402-60J --: 4M x 4-bit 60ns fast page mode DRAM in a 20-pin SOJ package, matching the density, speed grade and interface of the original Siemens part.
  • MT4C4001-60JC --: 4M x 4-bit 60ns DRAM in a 20-pin SOJ package with compatible pinout and timing, suitable as an alternative when the original is unavailable.
