The data pins are typically bi-directional in read-write memories. Memory Chips ROMs cont: There are several forms: For example, an 8-bit wide byte-wide memory device has 8 data pins.

2716 – 2716 16K EPROM Datasheet

Memory Chips The number of address pins is related to the number of memory locations. Programmers, components, and system designs have been erroneously suspected when incom- plete erasure was the basic daatsheet.

Extended expo- sure to room level fluorescent lighting will also cause erasure. No pins should be left open.

Field programmable but only once. Full text of ” IC Datasheet: Program Inhibit Mode The program inhibit mode allows programming several MMES simultaneously with different data for each one by controlling which ones receive datasjeet program pulse. Chip Deselect to Output Float.

Writing is eporm slower than a normal RAM. The pin and pin SIMMs are not used on these systems. More on this later. DRAMs are available in much larger sizes, e. In- complete erasure will cause symptoms that can be misleading.

Therefore, between 10 and 28 address pins are present. This is done 8 bits a byte datashret a time. The distance from lamp to unit should be maintained at 1 inch.

The table of “Electrical Characteristics” provides conditions for actual device operation. Reprogramming requires up to 20 minutes of high-intensity UV light exposure. The OE pin enables and disables a set of tristate buffers. Any individual address, a sequence of addresses, or addresses chosen at random may be programmed.

After the address and data signals are stable datqsheet program pin is pulsed from VI L to VIH with a pulse width between 45 ms and 55 ms.

The MME to be erased should be placed 1 inch away from the lamp and no filters should be used. Each memory device has at least one chip select CS or chip enable CE or select S pin that enables the memory device. Typical conditions are for operation at: The programming sequence is: These are shown in Table I.

Catalog listing of 1K X 8 indicate a byte addressable 8K memory. Factory programmed, cannot be changed. Table II shows the 3 programming modes. Lamps lose intensity as they age.

Common sizes today are 1K to M locations. The UV content of sunlight may cause a partial erasure of some bits in a relatively short period of time. An opaque coating paint, tape, label, etc. All bits will be at a “1” level output high in this initial state and after any full erasure. Multiple pulses are not needed but will not cause device damage.

Direct sunlight any intense light can cause temporary functional fail- ure due to generation of photo current. All similar inputs of the MME may be par- alleled. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. The number of data pins is related to the size of the memory location. MMES may be programmed in parallel with the same data in this mode.

The large storage capacity of DRAMs make it impractical to add the required number of address pins. The MME is packaged in a pin dual-in-line package with transparent lid. Erasable Programmable Read-Only Memory. Any or all of the 8 bits associated with an address location may be programmed wFth a single program pulse applied to the chip enable datasehet.
