KM641001BL - CMOS SRAM

Download the KM641001BL datasheet PDF. This datasheet also covers the KM641001B variant, as both devices belong to the same cmos sram family and are provided as variant models within a single manufacturer datasheet.

Description

The KM641001B is a 1,048,576-bit high-speed Static Random Access Memory organized as 262,144 words by 4 bits.

The KM641001B/BL uses 4 common input and output lines and has at output enable pin which operates faster than address access time at read cycle.

Features

  • Fast Access Time 15, 20ns(Max. ).
  • Low Power Dissipation Standby (TTL) : 20mA(Max. ) (CMOS) : 5mA(Max. ) 1mA(Max) L-Ver. Only Operating KM641001B/BL - 15 : 120mA(Max. ) KM641001B/BL - 20 : 118mA(Max. ).
  • Single 5.0V±10% Power Supply.
  • TTL Compatible Inputs and Outputs.
  • Fully Static Operation - No Clock or Refresh required.
  • Three State Outputs.
  • 2V Minimum Data Retention ; L-Ver. only.
  • Standard Pin Configuration KM641001B/BLJ : 28-SO.
