NTE2114 NTE-2114 | ECG2114 ECG-2114 | NTE Electronics NTE2114
Integrated Circuit MOS, Static 4K RAM, 300ns

Description:
The NTE2114 1024-word 4-bit static random access memory is fabricated using N-channel silicon- gate technology. All internal circuits are fully static and therefore require no clocks or refreshing for operation. The data is read out nondestructively and has the same polarity as the input data. Common input/output pins are provided. The separate chip select input (CS) allows easy memory expansion by OR-tying individual devices to a data bus.

Features:
- All Inputs and Outputs Directly TTL Compatible
- Static Operation: No Clocks or Refreshing Required
- Low Power: 225mW Typ
- High Speed: Down to 300ns Access Time
- TRI-STATE Output for Bus interface
- Common Data In and Data Out Pins
- Single 5V Supply
- Standard 18-Lead DIP Package

Functional Description:
Two pins control the operation of the NTE2114. Chip Select (CS) enables write and read operations and controls TRI-STATING of the data-output buffer. Write Enable (WE) chooses between READ and WRITE modes and also controls output TRI-STATING. The truth table details the states produced by combinations of the CS and WE controls.
During READ-cycle timing, WE is kept high. Independent of CS, any change in address code causes new data to be fetched and brought to the output buffer. CS must be low, however, for the output buffer to be enabled and transfer the data to the output pin.
Address access time, tA, is the time required for an address change to produce new data at the output pin, assuming CS has enabled the output buffer prior to data arrival. Chip Select-to-output delay, tCO, is the time required for CS to enable the output buffer and transfer previously fetched data to the output-pin. Operation with CS continuously held low is permissible.
Writing occurs only during the time both CS and WE are low. Minimum write pulse width, tWP, refers to this simultaneous low region. Data set-up and hold times are measured with respect to whichever control first rises. Successive write operations may be performed with CS continuously held low. WE then is used to terminate WRITE between address changes. Alternatively, WE may be held low for successive WRITES and CS used for WRITE interruption between address change.
In any event, either WE or CS (or both) must be high during address transitions to prevent erroneous WRITE.
