The read only memory cell usually consists of a single transistor (ROM and EPROM cells consist of one transistor, EEPROM cells consist of one, one-and-a-half, or two transis- tors). The threshold voltage of the transistor determines whether it is a. “1" or “0." During the read cycle, a voltage is placed on the gate of the cell.
DESCRIPTION. The M2716 is a 16,384 bit UV erasable and elec- trically programmable memory EPROM, ideally suited for applications where fast turn around and pattern experimentation are important require- ments. The M2716 is housed in a 24 pin Window Ceramic. Frit-Seal Dual-in-Line package. The transparent lid.
DESCRIPTION. The M2764A is a 65,536 bit UV erasable and elec- trically programmable memory EPROM. It is orga- nized as 8,192 words by 8 bits. The M27C64A is housed in a 28 pin Window Ce- ramic Frit-Seal Dual-in-Line package. The trans- parent lid allows the user to expose the chip to ultraviolet light to erase the
The M27C256B is a 256 Kbit EPROM offered in the two ranges UV (ultra violet erase) and. OTP (one time programmable). It is ideally suited for microprocessor systems and is organized as 32,768 by 8 bits. The FDIP28W (window ceramic frit-seal package) has a transparent lid which allows the user to expose the chip to
3. Memory. • Memory structures are crucial in digital design. – ROM, PROM, EPROM, RAM, SRAM, (S)DRAM, RDRAM,.. • All memory structures have an address bus and a data bus. – Possibly other control signals to control output etc. • E.g. 4 Bit Address bus with 5 Bit Data Bus. ADDR<3:0> DOUT<4:0>. 24 x 5 ROM/RAM
(EPROM). The device is organized into 64K words by. 8 bits (64K bytes). Accessing individual bytes from an address transition or from power-up (chip enable pin going low) is accomplished in less than 90 ns. This very high speed device allows the most sophisticated microprocessors to run at full speed without the need.

PIC16C5XX. This document includes the programming specifications for the following devices: INTRODUCTION. Overview. The PIC16C5X Series is a family of single-chip CMOS microcontrollers with on-chip EPROM for program stor- age. The programming specification also applies to. ROM products for verification only.
An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of memory chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile. It is an array of floating-gate transistors
