Instead, the address pins are multiplexed. Lamps lose intensity as they age. Direct sunlight any intense light can cause temporary functional fail- ure due to generation of photo current. DRAMs Pentiums have a bit wide data bus. The distance from lamp to unit should be maintained at 1 inch. For example, an 8-bit wide byte-wide memory device has 8 data pins.

All bits will be at a “1” level output high datashfet this initial state dtaasheet after any full erasure. Except for “Operating Temperature Range” they are not meant to imply that the devices should be operated at these limits.

Program Inhibit Mode The program inhibit mode allows programming several MMES simultaneously with different data for each one by datxsheet which ones receive the program pulse.

Therefore, between 10 and 28 address pins are present. The pin and pin SIMMs dafasheet not used on these systems. This exposure discharges the floating gate to its initial state through induced photo current. Used to store setup information, e.


EPROM Technical Data

To prevent damage the device it must not be inserted into a board with power applied. The programming sequence is: No pins should be left open. The MME is packaged in a pin dual-in-line package with transparent lid. The number of data pins is related to the size ddatasheet the memory location.

Any individual address, a sequence of addresses, or addresses chosen at random may be programmed. An erasure system should be calibrated periodically. More on this later. If more than one are present, then all must be 0 in order to perform a read or write.

The OE pin enables and disables a set of tristate buffers. Common sizes today are epgom to M locations. Writing is much slower than a normal RAM.

Field programmable but only once.

The table of “Electrical Characteristics” provides conditions for actual device operation. Maintains its state when powered down.

Memory Chips Each memory device has at least one control pin. Catalog listing of 1K X 8 indicate a byte addressable 8K memory. There are several forms: Multiple pulses are not needed but will not cause datasehet damage. The data pins are typically bi-directional in read-write memories. Erasable Programmable Read-Only Memory.

It is recommended that the MME be kept out of direct sunlight. Full text of ” IC Datasheet: A new pattern can then be written into the device by following the programming procedure.


IC Datasheet: 2716 EPROM – 1

Any or all of the 8 bits associated with 2761 address location may be programmed wFth a single program pulse applied to the chip enable pin. Table II shows the 3 programming modes. This refresh is performed by a special circuit in the DRAM which refreshes the entire memory using reads. Factory programmed, cannot be changed.

MMES may be programmed in parallel with the same data in this mode. The board has DRAMs mounted on both sides and is pins. The erasure time is increased by the square of the distance if the distance is doubled the erasure time goes up by a factor of 4.

Transition times S 20 ns unless noted otherwise. All similar inputs of the MME may be par- alleled. Chip Deselect to Output Float. Memory Chips The number of address pins is related to the number of memory locations. Typical conditions are for operation at: An opaque coating paint, tape, label, etc.
